    Today was a very special day. They say, never meet your heroes but today I met the man, the myth, the Legend of the Spritzer. I flew down to Reykjavík to deliver the first production RR1 to ever leave Indian shores. It was an honour to meet Birgir, I still remember reading his posts 7-8 years ago when I got into the hobby and owning an Electrostat seemed unfathomable. So, delivering my Headphone to the STAX Mafia is an occasion to celebrate. Had commissioned 2 custom KGSSHVs. Our primary Amp of choice for upcoming shows. Really fortunate to be lucky enough to visit Iceland. Even though it was a short business trip, will be back with the family someday.

    This is going to be tl:dr for many, but Steve and I have delivered the first completed project from our Shelter Shop. By far the biggest woodworking project I have attempted, and both Steve and I are very proud of the results. Steve, Claire and I promised to build a dining room table and bench as a wedding present for Claire's sister and her new wife. Here are some pics during the process of building through yesterday's delivery. I forgot to take pictures of the 8/4 (aka 2") cherry wood boards before we started milling them down, but the lumber was excellent. We only ended up with one board that was twisted a bit, and we were still able to use it. Here is a board after some planing for thickness, and you can see the planer snipe several inches from the end, which we cut off anyway. After planing and then jointing an edge, we chop sawed the boards to rough length and then cut them to width on the table saw. The top is four boards and the bench is two. Next, we cut in mortises on the mating edges of the table and bench boards to receive floating tenons. I forgot to take pictures of that process using a Festool Domino machine, but you can see the mortises in the first picture below. That is the two halves of the table top being glued up before gluing them together later. After everything was glued up and cured, we used a track saw to cut them to final length and width. All edges have a 15 degree angle, which turned out great. Next up was sanding and finishing. We sanded from 80 or 120 through to 320 grit, and the cherry was smooth as a baby's butt. We then applied two coats of raw linseed oil followed by two coats of Tried and True original finish, which is linseed oil and beeswax. Ultimately, we also put on a coat of carnuba wax because Thos Moser does its oil finished furniture that way, which is good enough for me. Here is a piece of raw cherry next to the bench top with some linseed oil applied. This is the bench top after the first coat of Tried and True. This is great stuff that Doug introduced me to, and I love. You don't even need to wear gloves it is so natural and your hands feel better after applying some than before. We bought metal legs for the table and bench from a seller on Etsy, and they turned out to be even better than expected. We decided to rout out the underside to accept the base plates, and we also used threaded metal inserts so we could use machine screws rather than wood screws. It is very sleek and worked beautifully. We assembled everything at my house to make sure it was all good, then wrapped it up with moving blankets yesterday for delivery. We haven't been around my sisters in law for a couple of weeks so we took precautions and wore PPE. The table and bench look pretty stunning in place, and like I said, Steve and I are very pleased with the outcome. The happy couple are even more thrilled with the finished product and have been obsessively looking for the perfect chairs to complete the set. The cherry will darken over time and will only become more beautiful. Another great thing about the Tried and True finish is that it can be maintained with an occasional waxing, or it can be freshened up or repaired if necessary without the need for stripping the original finish first. From buying the lumber on March 20 to installation on April 5 is pretty quick work. Now, we have to finish another project already under way, and then move on to other projects. This Shelter Shop will stay busy for the duration, assuming we both stay healthy. Thanks for reading if you got this far. 😁

    Not today, but yesterday. Completed the Kelly Brush Century for the second year running. Trained hard, cut about 30min off my previous time and had a ton of fun with the same group of guys that I've been doing these rides with for the last 7 years.

    I posted a Chinese version of this article several months ago and now I translated it and put it here. I guess some people here will be interested. I hope you like it. Actually I have some more articles like this pending but I just don't have the time to write it up. --------------------------------------------------------------------------------------------------------------------------------- It all started about a year ago that a second hand sr-omega popped up in the local community. From time to time omegas show up on markets around the world but this one is different: an omega with 007 drivers installed. When the drivers are replaced, such omega drops its value to a fraction of its original. The seller listed it for 48888 RMB initially and sold it for like 20000 + at the end. When I first saw the listing, the first thing that caught my attention are neither the price nor the 007 drivers but one accessory laying aside, which is a pair of dead drivers I have never seen before. At first sight I know that it’s a prototype, a true unicorn that probably only one pair exists in the world. I am so curious on how it sounds and how it compares to 007 or 009 or the original omega. I messaged the seller right away and after some persuasion and explanation that I can give this driver a next life, I got it at a reasonable price. And it has become one of my biggest regret that I didn’t also purchase the omega itself that time, otherwise I can put it back into the place where the drivers belong to. Here is the driver itself. From this driver you can see several innovations made by Stax that has never been seen in other Stax models before it. The diaphragm is identical to a normal omega but the electrode is totally a different creature: copper plate similar to lambda sig etc. but much more refined. Over different regions of the electrode the thickness is different. The thicker copper comprises of the # pattern skeleton to give the rigidity while the thinner copper is perforated. You can see the same topology on 009 and 009s where they claim to have the MLER welding technology employed on the electrode. But this omega prototype electrode is in one piece and just as thick as a credit card. Furthermore, they rounded the edge of the perforation like what Stax does on 009S. Stax even make a sectional view illustration graph on their 009S promotion leaflet. Such treatment helps sound to radiate. To me it’s really impressive to see some characteristics of a flagship model today on a 30-year-old design. I wonder what the R&D department has been doing in these years But afterall it’s a prototype. It does have some problems: this electrode is too thin to give enough rigidity and prevent bending. They are curved to 5 o at most. Moreover, the area of attachment between the frame and the electrode is too small. It just peels due to aging. I see such defects in some modern designs too. Although its reasonable to have these issues because its 20+ years old, it does reveal that the one who designed it is not thoughtful enough. Perhaps that’s why it was never released to the market except the one on my desk. Besides the defects the design has, the driver itself is at a very bad condition. The drivers have been exposed to the external environment, so dust gets onto everywhere. The one who does not properly seal the package probably has never imagined that this driver will be repaired. It’s a pain in the ass to make the driver dust free again, especially when they are on the very fragile diaphragm. Normally I don’t accept requests to repair an exposed driver and I will give a new quote to clients who send me an exposed e-stat without telling me in advance . But I own this driver and I can bear the risk so that’s OK. The four electrodes are bent in different direction and magnitude as well as having detachment and failure of epoxy. Taking it apart and bent it manually is the only way out. It takes a lot of skill to bend a bent copper plate. Like you have to apply a certain amount of force on the copper and then you check how you have bent it by eye balling or a ruler, and you repeat this process a dozen times on one plate. You make it worse if you don’t know how. The most challenging part of it is that how much you bend an electrode actually affects the sound pressure on one side of the driver so at this point you just have to guess. I have neither the tool nor the file of the design, its all hiding in somewhere inside Stax’s archive library. At most of the time repairing a e-stat is more challenging and troublesome than making a new one. Aging will just make everything a mess and sometime you have to wipe the ass of someone who does not make the design good enough to withstand usage. Solvent removes dust and grease on the driver. It gets much trickier when it comes to cleaning the diaphragm. Effectiveness of a method to clean the diaphragm is an issue when there is just too much dust, not to mention the risk that you will break a diaphragm by puncture or sketch. At the end I decided to clean the diaphragm with solution. Although it will damage the coating, it means nothing to me as I can recoat it anyway to replace the old one which is probably damaged anyway. Cleaning done. They took away the dust screens so I have to prepare these as well. Last Step: assembly, the most important part of all steps. This several hours of work determines how long a driver can last before imbalance or noise occurs. Its my duty to make sure every edge and surface inside the driver is dust free. If not, dust will eventually get onto the diaphragm at some point in its service life and short the electrode and the diaphragm. Practically if the pollutant is much smaller than DS gap 0.5mm then its fine. All these procedures are done in a dust free environment. Soldering work Omega adopted a spring mechanism to connect the bias supply to the diaphragm. It is shaped like a tuning fork and it is odd (photo credits to audiohobby .pl ). I tried to make one but it just can’t grip firmly. After some days of having this troubling me I figured out a way, using HD600’s spring and I glad that it worked, at least for now. I used 007 cable, lambda sig headband, cnc machined and anodized aluminum casing and tailor made earpad. I am a proud Omega owner and I shipped the earpad for a clone. The result is satisfactory. I took away the back grill for inspection but I am kind of regret because I cannot put it back. The general sound signature of this omega prototype is somewhat identical to the original: natural, airy, transparent and clean. Its free of unnaturalness which can be found on 009 (please forgive me if you find this statement irritating, afterall the perception of sound is subjective). It has a larger soundstage than 009 for sure but I think 009 has more details than this one slightly. To me this prototype takes a midway approach between early-SN omega and Late-SN omega. It has a bit of the sweet coloration of an early omega while having much of the naturalness of a late omega. I found that early omega has a huge, diffused soundstage while a late omega has some in head effect which is unpleasant to me. Luckily this prototype is more on the early side. But still this prototype is different from the two regrading the proportion of width and depth of soundstage. I can’t explain more because I haven’t AB compare yet. What amaze me the most is how the prototype omega differs from the typical omega in the dynamic and bass region. The normal omega gives me an image of mellow, soft and relaxing in the bass region. Although 009 and 007 has better bass and impact I like the stress-free presentation of the original omega. The only thing omega put stress on me while I am wearing it is its price. In the prototype omega, I feel an enhancement on the impact, the speed and the amount of bass. Perhaps it’s the reason why they create this prototype, to improve on what the original is lacking. The density of imaging of sound also improves by a bit. Be caution that I cannot remove the effect of the different earpad and casing on the overall sound comparing to the original so the effect I mentioned above might be due to them. Despite all these merits, there is something lacking in this prototype: The openness of soundstage and the super-revealing details on the original omega. If omega scores 100 and 009 scores 85 in the aspect, I will give a 95 to this prototype. The transition from mesh electrode to plate electrode seems to be a double-sided sword. I remember in one of the Stax staff interviews they explained on Pros and Cons between mesh and plate electrodes. You give up something to exchange for another. Nothing is perfect unless you pay a double.

    This has been a killer of a week for me so I'm late with the impressions. Then all of sudden we had a holiday today so I finally have some free time. I'm too lazy to find my camera so I'll take some pics later. First off, this is set nr.4 so I very much view it as a "work in progress" but...they are pretty awesome. From the first impressions and until now they keep reminding me of the SR-007. Clearly power hogs (I measured the system with stock cable at 160pf) too and a bit dark sounding. Now in my book this is a welcome reprise from all the bright models out there now. Doesn't mean the treble is subdued or anything like that, it is just not as apparent as with the L700 or 009's for instance. This also gives it a fuller sound and well...that bass. The cups are ported so the bass could have been compromised due to that but not so here, it's deep, tight and tuneful. It doesn't match a closed SR-007 but I frankly don't mind that...I can always grab my 007's if I want to listen to them. These are a bit more tuneful with more presence higher up. One of the first tracks I tried on them is the one which 009, 009S and 009BK all fail miserably at, but no issues here. They replicate the snare drum perfectly and same goes for everything else I've thrown at them. The midrange is perfectly fine and really showcases the difference in mastering on some tracks. The soundstage is just about perfect, follows what the tracks should sound like and doesn't pull a HE90 on us. Not quite up to the layering of the 007's but then again...that is the gold standard. Overall they are very neutral and do what any transducer should do, get out of the way. For me the biggest compliment to any headphones is me willing to listen to them as well, I have a lot of headphones at hand. I've used these almost exclusively since I got them, only swapping out to do comparisons. Now for fit and finish, I have no complaints. The headband is very sturdy with nice spring steel for the main span and they fit my head nicely. A bit snug but then again, I have a melon for a head. I did bend the arc a bit and now I can use them for hours at a time. The housing is attached to the earcups with a single M4 bolt and I did experience some rubbing there. This joint wasn't really supposed to move but for my use, they fit better that way so I place a nylon washer between the two parts and that has fixed this. I've already relayed this to Aumkar who should be arriving back home soon. The only major issue I've had is with the cable or rather one of the connectors. One channel started to drop out and after some troubleshooting this was traced to the mini XLR plug. I bought some new ones and made a quick replacement cable this morning and now it works perfectly. To keep the cost down the mini XLR does work for this but yeah... I'd like something better but given the cost constraints I get why they use it. Same for the cable, getting anything which works for this is difficult and costly. The cable is still better than what Hifiman are using so yeah... I'm not too worried about that. So over all, I'm very, very impressed and I will be working with Aumkar to see if we can't improve on these small issues.

    I put on my investigator hat and solved the case of the missing trash can lid. For those still on the edges of their seats. The lid was found and using an 8’ Heavy swimbait pole rigged with a GoPro case I was able to cast, first try, the case right into the middle of the floating lid and reel it back to the edge of the lake where Kasia retrieved it with a stand up paddle board paddle.

    Met Aumkar and listened to the RR1 at CanJam today, two very pleasant experiences. The headphones sounded really nice out of both setups, one a KGSSHV (from birgir I think) and the other a little koss amp (the one that goes with their headphones, Massdrop version). I had a very pleasant listen with the smaller setup being run from an iBasso DAP (maybe DX150). I seriously would have bought that whole little setup on the spot for listening on vacation or the office. It had excellent bass and an extremely musical, engaging sound. I'll probably buy a pair of these when they are for sale. Aumkar is a great guy! Thanks for the overview and good luck.

    Not quite yesterday, but last week. What passed for grass in our garden was 50% weeds and infested with ant hills that defied all attempts, chemical, biological and thermal, to kill off. So after three weeks of preparation (painting 35 metres of fence twice, painting walls white, all after digging out 15 metres of Virginia Creeper and ivy) a team of five guys came for four days to fit artificial grass. Cheap it was not, but the effect is so much better that the mess it replaced.

    Today we had probably the most delicious and certainly the most expensive lunch of our lives at the two Michelin star restaurant at Bernard Magrez's La Grand Maison. Before we ordered anything, five or six plates containing at least seven amuse bouches arrived, along with suggested order of consumption. I got distracted and forgot to photograph them. We went for the six course lunch with wine pairings. Dessert was actually five different desserts each followed by two more treats to amuse our bouches. Extraordinary food paired with incredible wines. I also forgot to photograph the rump of veal. Dommage.

    not going to create a new thread... figured i'd drop some simple thoughts on the Focal Elex that arrived last week. i decided to grab these after reading ample comparisons to Sennheiser and the notion that these are more energetic with better low-end with some semblance of HD580/600/650 balance. my 580's have sounded so good out of gilmore lite mk2 that this intrigued me. all of the below is my direct thoughts vs. HD580. treble is not as lush/obvious and vocals are slightly recessed... i think it's because of the slight upper-mid dip or whatever the fuck that people have measured on both Elear and Elex bass is drastically better in every regard (quantity, detail) imaging/positioning is a fair bit better and soundstage is wider but not much deeper ^because of all of the above, i think i find these slightly easier to listen with across all genres... read a lot of stupid comments that Focal isn't great for electronic which i could not disagree with more. and much better with rock/metal because of the better low end and tweaked treble. they're not bright and they're not fatiguing. couple other things... fit is good, takes 45 minutes or so before i get a hotspot from the headband because of the weight but no biggie. and these have probably the best finish i've ever experienced on any headphone. ever. i cannot make a single critique of the build quality and anyone who does is a bitch. also all black, murda'd-out headphones are dope. @Dusty Chalk #amirite that's all she fucking wrote. these are the first comments i've typed up for a headphone in nearly 10 years so they must have made some kind of impression.

    It was awesome meeting you and getting the headphones hand-delivered. My impressions will be coming soon but a small sneak preview after a very limited time with them (aka I couldn't help myself), don't let the price fool you to think these are budget headphones...they don't sound like that.

    Firstly many thanks to all the contributors to this forum whos posts and direct assistance helped immensely with my amp build, there were a few issues on the way, but the amp is functioning perfectly and is a huge improvement over the STM-727II it replaces. There are many far more seasoned builders than I, but hopefully by mentioning a couple of issues I encountered it may help any future builders. 1) Check and double check your resistor values - I missed one and it resulted in quite a few replacement parts being needed. 2) If you are going to check voltages using your probe on the top of the screw terminals, tighten the screw down first (changed out the original 7815 regulator thinking it was faulty as a result) 3) You need the OP27 opamp installed even if you are using the opto servo to control offset. 4) The posted instructions mention adjusting the left channel balance and offset - you also need to perform the same operation on the right channel 5) I bought an inexpensive set of high voltage 12kv linesmans gloves from Amazon. Probably overkill but for the initial power up of the boards gave me more confidence in working with HV supplies. 6) Mentioned in another thread but Arrow Electronics offer most parts that Mouser have at lower cost and with free overnight shipping 7) If you need circuit boards, Easy EDA is pretty good at circuit layout and integrates with board manufacturer JLCPCB who are really inexpensive (read $2 for 5 small boards) Differences from what I would consider as standard build included: Replaced the 7815 and 7915 with AMB Labs Sigma 78 and Sigma 79 drop in circuits - soldering on the miniscule SM components is a challenge but aside from that they work really well. Used a ladder attenuator from Acoustic Dimensions, made a custom PCB to connect to it (I have 3 spares if anyone needs one). Installed input switching between single end and balanced, with also a feed through setting where the KGSSHV is totally bypassed. The SE input setting also connects the SE ground to the amps -ve balanced input. Picture is the KGSSHV Carbon with it's sibling a TPA Buffalo ESS9035 DAC built last year. Cheers Martin

    Not today but over the course of the last week, finally got to use the Shapeoko to actually make something. A coworker from the central office is retiring after 46 years of Government service. I decided to make her a custom plaque. First prototype It's basically a relief of the island that the Shipyard is on. Prototype #2 Figured out that I was having some issues zeroing the Z axis, which were entirely user error. ?‍♂️ Final version: I got the shipyard to engrave the small brass tag, I haven't gotten to the point where I can do that yet. Next up, some signs for the local MTB trail network.

    Well that was a totally awesome concert - The Eagles in Birmingham (the UK one). Two and a half hours with no break - basically their iconic Greatest Hits and Hotel California albums (which I bought back in the day and still have) and a whole load of other, quite advanced sonically, stuff from later albums. The line up was the only remaining and performing member Don Henley (71) and slightly later members Joe Walsh and Timothy B. Schmidt, both also 71. Singing Glenn Frey's vocals was his son Deacon Frey (26), who was superb, and much to Carole's delight - Vince Gill. And the guys had lost none of their vocal ability and high notes despite their advancing years. It was the nearest thing to a hifi concert I've been to - the sound quality was excellent. One hell of an evening. This was the set list: Take It Easy One of These Nights Take It to the Limit Tequila Sunrise Witchy Woman In the City (Joe Walsh song) I Can't Tell You Why New Kid in Town Peaceful Easy Feeling Love Will Keep Us Alive Lyin' Eyes Don't Let Our Love Start Slippin' Away (Vince Gill cover) Those Shoes Already Gone Walk Away (James Gang cover) Life's Been Good (Joe Walsh song) The Boys of Summer (Don Henley song) Heartache Tonight Funk #49 (James Gang cover) Life in the Fast Lane Hotel California Rocky Mountain Way (Joe Walsh song) Desperado Best of My Love

    Performing last minute gear tune-ups for Lance and his competition in Columbus. Received word last week that Lance has been named to the USA Fencing All American first team and USA Fencing All-Academic first team for this year. Hopefully if he has a good competition these recognitions will help when he meets the college fencing coaches he has scheduled with there in Columbus. He is scheduled to fence Junior Men’s foil, Junior Men’s epee, Senior Men’s foil and Division I Men’s foil. Division I will be the toughest because it will have all of the best college fencers and three US Olympic fencers competing. This is a very tough schedule so hopefully he can hold it together and feel good about his performance when it’s done. Yikes!

    Just finished testing a new version of the battery with the LT1021-7 reference. From what I can measure, it seems quieter on the scope (mostly above 25KHz) than the LED version. It's nice to be able to test without risking the whole amp I'll probably start using the LT1021-7 in the GRHV supply as well since it needs less current to operate. I'm currently feeding it about .94mA with the base of the transistor it connects to pulling about 70uA from that as well.

    Karen and I "Met the Fokkers" last night. Our son Andrew has been pretty serious with a wonderful young lady he met at college. The great news is that her family lives 2 towns over from us, so they can see each other easily outside of the school year. Amy is going for 8 weeks to special program in Kenya this Summer, and she and Andrew thought it would be great to have the parents meet. Simple dinner at Bertucci's, but it was very successful, we enjoyed the company and chat very much. It helps that the father works in IT like me, has a slightly similar sense of humor, and looks just a little bit like Peter in Family Guy ? It just felt very normal and pleasant, and the fact that it was the kids' idea made it even more special....
