Headphone Amplification

If anyone's interested, there's a good deal on Gilmore Lite over at Audiogon. I'm not associated with the seller, and would've bought it myself if I needed another amp. http://cls.audiogon.com/cgi-bin/cls.pl?ampstran&1197940150

website The short write-up in December's issue of Hi-Fi Choice says, "...by using CRT technology, these valves can be run at a lower power and offer significantly improved lifespans." That'd be the part that got my attention.

hi everyone, i m torn between building an ehha and an aikido and the lack of info about them(especially aikido) has led me to ask for a comparison between the two. i d be using the ehha with a sigma22 and the aikido would be broskie latest octal lsa/hpa all-in-one(because i have a couple of sylvania and rca 6sn7 doing nothing in my wardrobe). comments on any aikido amp would be welcome as well. i m opened to other tube amps but those two seemed the best to me as far as i looked. if it can help i have a beta22 and a dual darkvoice 336i that you can compare with. any input would be appreciated

What do you guys think about these 2 amps coming out soon? Not much info on them. Basically, i'm wondering if anyone can give some insight about the quality of their products and whether these 2 new amps will be worth checking out.

Hey all, first of all, I've searched. Now, picked myself up a CA Azur 840C yesterday and want an amp to match. I'm using modded Denon D5000's. I tend to prefer SS over tubes as I'm a detail/analytic freak. A rule of thumb I assume holds is that the amp doesn't cost more than the source, so that limits the playing field to $1500-ish, which is more than ridiculous for an amp mated to a $1500 source IMO. I was thinking used GCHA, but want to know what others suggest. No op-amps here preferably, unless the circuit is well designed, and designed for said op-amp. I looked into a B22, but don't know who I can get to build one. I'd DIY it, but don't know wher…

Just wondering, what are some good tubes for an MPX3 for metal? It sounds really good and realistic on most things so far, but the liquidic presentation doesn't lend itself to metal so well. Or should I just get a grado? Also, any recommendations for the W10LTD? I know not that many people have heard it, but it's one of the AT's that leans a bit more to the w100/2002 side, but not too much. My sonic preferences would probably be at least a realistic amount of bass, and "searing soaring highs"/

All I remember was seeing a MOT thread in Head-Fi several months back. It looks like it's been released, but I can't seem to find anything about it. So I take it no one has heard this anything anywhere?

I had a fun 20 mins chatting with Mikhail, speccing up a high voltage Supra for my newly acquired R10's. After saying 'yes' to most of the options (mostly having Blackgates all around), two things that were sticking points for me were the Plitron transformer ($900 vs $250 for an upgraded Supra Transformer) and Audio Note coupling caps (again around $7-900 - bit hazy here, vs $360 for V-Cap Coupling Caps). My question for those who have been able to do a comparison, is what difference does a Plitron transformer or Audio Note coupling caps make and is the extra cost worth it? If you had to choose one upgrade, which would it be? I'd appreciate your thoughts on this …

Has anyone has experience of them?

I've recently purchased the C&C BH from ebay and it doubles the perfomance of the JDSLabs C421 for almost half the price. It's a top amp. Battery last 80 hours from a single charge! I can't wait to put my hands on the $300 C&C XO2 for an A/B. As we proceed I'll let you know more details about this little gen, that beats amps that cost twice as much. It has the performance of $300 amps, with the resolution/detail/clarity of much more expensive amps. If you live in the USA you can get it for just $99 and odds are that in your country you don't pay customs tax. I think the same applies to Australia. The C&C BH is a BIG BIG BIG step up from the FiiO E11. I…

Well, I've been tossing around the idea lately of getting a new amp and source. I plan on selling my DAC and putting the Millet on preamp duty for my future HT setup. Right now I'm really looking into the Headamp GS-1. I need an amp with 2 inputs and prefer preamp capability (but don't need it), and the GS-1 also has two 1/4th outputs with a line out. As for a source, I'm looking at the Cambridge Azur 650C from Audiocubes. Other than the GS-1, I'd be interested in a SLAM from Mikhail, or maybe something from the DIY garden (Dynamite?). I'll use my 0404 and possibly the 640C as sources, and would like to use the preamp feature to drive a T-Amp and my Paradigm Atoms. …

Done by a 3rd party who happens to own both units. Someone I trust who has no hammer to pound with. I see no reason not to post this, as it should be clearly duplicatable by just about anyone. http://gilmore.chem.northwestern.edu/picovspredator.htm

Was expecting to find a Head-Case melodrama thread about this amp here, but it's not the case. The inane banter and debates on the Head-Fi Phoenix thread about CAST, DAC, etc, makes me skim alot and not read much there. This amp's two box layout is rather interesting to me. Without really knowing too much about the actual circuit, the build quality looks pretty impressive to me. Seems to be an ideal layout for me as well, as I don't like full wdith stereo components. Digital volume control and inputs galore are a plus. One issue I have is the internal conversion to CAST, and how it's converting single ended to balanced. More info and pics here: [url…

I have a 007tA that lost the -350V. Looks like the 150ohm filter resistor between the two HV caps is open. There also seem to be something loading the bias voltage. The voltage before the 4.7M resistor in series with the output socket measure 300V after the resistor but 400V before the resistor with nothing connected. Searching thru the forum seems like there is a 007t schematic available somewhere but all the links in previous posts are no longer valid. It would be most helpful if a schematic is available. Would like to find out what causes the 150ohm resistor to open before replacing it. thanks.

which solid state amp should i go for? the 717 or the KGSS? i know a stock kgss is 1.5k but i don't know how much does the 717 cost...

OMG! OMG! I just got my "PimplePopper Super Micro Mini Xtrasmall" portable amp and my "Boil Buds" headphone buds. It's the best I have ever heard. It's even better than the Sony ear buds. I delivered a lot of newspapers to afford this. My mom says I should have put the money aside for colledge. I told her that I am only 28 years old and have plenty of time to save for that. Right now I am in heaven. After break in I will give a 150 page review on both items.

I just fired up my spanking-new Rockhopper M3 (Thanks, Stephen!). Power is good. My k701 almost sounds bassy! My k271 almost has slam! My crappy music sounds slightly less crappy! There is still treble! I'm not even drunk yet! I have a half fifth of Gentleman Jack on my desk! If I had only known what this could sound like I'd have ordered one a year ago. I really hope this doesn't mean a β22 is in my future.

I need an amp that doesn't have an IEC connector at the back, only a DC input. Does this exist? If not, this should be easy to drill a hole and hardwire?

So I've been able to recently acquire a used KGSS. Using it with my 404LE, but I got it in anticipation of trying a 4070 and/or O2 at some point. It supposedly has a stepped DACT attenuator added (as original attenuator failed). It has some very noticeable static when I turn the volume knob, especially between each notch, but goes away completely when I set it at any specific volume level. The seller specifically disclosed this before the purchase, so all is good. I can live with it, as it sounds so good with the 404LE. My question is - in the future, if I wanted to eliminate this minor flaw, is it as simple as replacing with a new quality attenuator? (I'd have …

Can you help me with schematic of Stax SRM007tA amplifer please ? (100 V Japan version)

You guys are mean. You should also mention weather conditions. Yes, there was weather. No, I don't remember what it was. Here it is, for those of you even lazier than I.

Hi everyone, I'm about to enter the world of tubes. My Acoustic Zen's arrived, and I'm going to be powering them with one of these http://www.gini.com/index.php?id=250. I heard the combo at a local dealer and really fell in love with it. Can someone explain me the difference between 'triode' operation and 'ultralinear' operation, and also recommend some really great tubes. I'm a complete newbie in this field so go easy!

Hi! i would like to share my work with you. I made an dynalo amp powered by grlv power supply and a pcm1794a/cm6631a dac. Everything is totaly made by me. I also designed the pcb nd ordered it from JLCPCB. Amp offset voltage stays at max +-1mV and it is totally silent. Case is DOUK AUDIO. pictures: https://drive.google.com/drive/folders/1a6cbGFpN6s5EadR8DA_lb21ZFwOwzK4R?usp=sharing

Dear All Due to sudden voltage spike last night - my stax vaccume tube amp srm007TA diode burnt out. Can you guide through the process to fix this issue? I have attached the images below for reference. Hopefully the PCB seems to be intact. But i am not a expert and any advise is highly appreciated Thank you

Has anyone used these in any amp? Are they worth the premium price?
