Headphone Amplification

The impressions will come late tonight or sometime tomorrow after I get around to listening to it in a short while. I'm over at Roam's place and we just finished de-fucking one of my tube amps.

hi. Okay, here is the low-down, I'm borrowing the F1 from Humanflyz. I connect the F1 to my ZD as a pre and then the K1000. However, I get a hum. where is it coming from? Well, i switch sources... that's not it. I turn the volume all the way up on the ZD and it's still the same (meaning it doesn't originate with the ZD). The only other option is that the F1 is the cause. Since i didn't hear it at Mike's, i'm sure I must have caused it. the issue here is whether the problem is caused at the "power" source (since i'm connecting it to a general 5 outlet power strip) or the PC (since it's just a standard computer Power cord). The other option is that i may be gett…

CANOR-AUDIO.COM : Headphone tube amplifier SH1 : Tube amplifier & high end audio found this while following random integrated amp links. any thoughts? construction looks clean. worth the $550 they charge for it?

HEADAMP GSX #001 (Alaska size pics) A few shots of the long awaited GSX in my rig, just opened the package,setup her up, and took some shots...for you people of course... Now if you don't mind my ears have a date with her and I am not wasting no more time! I know they are sloppy but I got an important Date now...byebye and enjoy

Hi guys. I just bought a Stax SRS-005 system which consists in a SRM-Xh amp and SR-003 earphones. After some time spent on thinking, I've decided to experiment some configurations. Basically, I'm looking for a better amp. I know the SRM-Xh is a vintage amp, and there should be better alternatives to use with the babystax. I'd like something that's an upgrade over the stock SRM-252 amp. I have been advised towards the SRM-313 as a good match, but I'd like to know if there are any others. I really want to exploit the best potential of the sr-003, especially since they tend to be dark, while higher models, like the Lambdas, tend to be very forward in the upper midrange, w…

Earlier today I came across the pictures from ETF '07. http://www.dhtrob.com/etf/index.php?start=23 This is a picture of a totally out there headphone amplifier using transmitting tubes. Those tubes are around 7" tall, and the plate dissipation is up to 100W. For a pair of headphones. And though it's not a headphone amp, this is just stunning.

I caught this off of Ryan's review -- when did this come out?

I'm interested in a very small foot print of an amp. I like a warm colouration when I'm working. I will likely be using the RS-1's and the RA-1 will be far too lively. I would love something with tubes, but the EMP AE is too rich for my blood and well, out of production. THe RKV is very interesting but quite a bit larger. I will be using an iPod.

Has anyone heard this amp with AKG K701's? Does the amp have enough output to drive them to decent listening levels? Looks well built. How does it sound?

Ok, am wanting the SR-L700 model and am TOTALLY confused as to which damn amp to get, we have the SRM 006ts, 353x and 727 mk 2 . Are tbere any other brands that can be better suited up to this price ceiling?

I was wondering if an amp designer/builder can explain why so many people have problems running the hev70. Most of the are imported from the EU and it seems to be all sorts of problems yet they work fine in the EU. Is there any possible explaination for it?

http://tubecad.com/2007/08/blog0117.htm Woo! I wonder how it would do with Grados.

Arrived on Thursday, I got it on Friday: I've had a couple of days to listen to it, and it really is a superb HD650 amp. Reminds me of the first time I fell for the HD650 with the PPX3 Slam. Impossible to say which is better since I haven't owned the PPX3 for over a year. The bass is in total control and reaches lower then I recall it ever reaching (I have actually turned around a couple times to make sure my 22Ls weren't on). The amp makes the HD650 do all those lovely audiophile things, like create a nice space around guitar plucks and the like. Also does a damn fine job of recreating electric guitar crunch. This amp has certainly made rediscovering my HD650s…

Hi. I'm looking for a good value amp in the under 800$ price range. I have been adviced to get an HR-2, a Gillmore Lite and M^3. While I am not sure I want to spend 850$ for the HR-2 (plus I've read some constrasting opinions about it), I'm seriously considering the Lite with DPS and M^3. I like the fact that the former is only transistor based, but it has been described as hyperdetailed and somewhat piercing in the highs by more than a few people on Headfi. Considering that I can't stand sibilance/harshness, I am not sure if I should go on with it. I read here that the M^3 is on the "warm" side. I am not sure if I am going to use Sennheiser HDxx or Denon D5000 with it. …

I'm working on a person's Minibox E. What do these things take for a battery charger (he didn't send it). I think I got it fixed (self-inflicted from said person "rolling" the opamps), but since the battery seems to be drained, I can't test it without a bit more knowledge. Any schematics for these floating around? Seems to be rather similar to a Mint (and therefore SR71, etc.), but no rail splitter... must be using a pair of Li Ion with the ground taken at the junction (3 wires coming off the battery pack).

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 …

At what point should you start to worry about how hot your amps (and other components) get? For example, my HR Balanced desktop runs hot, as expected, and so does the Desktop Power Supply. Further the DAC1 also runs pretty warm, which is also expected. Regardless of the fact that it is expected, it still concerns me. Should it? At what point do you consider the heat as a sign of a problem, or the imminent cause of one. Er, aside from fire that is.

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. …

The old website says that there's a new website coming, so for those of you in the know, is Craig going to reveal some new products?

This probably dives me more insane than anything else about this hobby/obsession. So I finally make the switch and have all my music into a 5g iPod 60gb, I get the awesome Turbodock II for the line out and am using my fully burned in Hornet. The Hornet sounds awesome... nice texture, black background, good weight/depth, etc. So why did I put it on eBay... I miss the crossfeed and bassboost from my SM for some of my music. Damn I hate this! I wish I could keep both but without the parametric EQ some of the music I listen to sounds slightly too dry with this amp, which is frustrating because I'll switch to a different album and it's bliss! So off I go to sell and on…

Anyone here have any info about this tube? I read somewhere that this is a higher quality 6AS7G but upon inpection, I see that it has 5998 plates. This is where I'm confused: Is this tube supposed to sound like a 6AS7G or a 5998? BTW, I got my Chatham 2399s when I got my Extreme used and I like it....spacious and detailed but the 7236 trumps it in speed and punch.

Ha! ... gotta love the Gilmore Raptor

Took my Cary 300sei out of the garage not heated where it has been unused for over a year, amp was pretty cold temps in the high 40s. I should have let it get to room tempature but I didn't Amp turned on got a hum from the transformers I really never noticed before,Input tubes light up but My WE300bs never light up. Ideas? I have another set of we300bs ,but I don't want to take a chance installing them. I don't have any cheaper tubes to try.
