Headphone Amplification

Ahoy mateys! Paging jpak & hirsch, and anyone else who cares to chime in. Looks like I've got a touch of the microfonick in the left channel. Don't notice it at all when music is playing, but when I plug in the cans I can hear it, and after the cans are plugged in, I can tap the volume knob and hear it. No worries though, gave me an excuse to crack open the SHA and see what was going on inside. First, off topic, this amp is dusty as hell, boy. What is a safe way to get rid of this dust? Just some standard compressed air (pc duster)? But on topic, the tubes that were in there were some JAN Phillips 6922s, which sounded fine, but of course I'd like to experi…

Hi I am going to build energizer for Orpheus and Stax with LL9202AM. For Stax I will copy PSU Bias from T1. I wonder if I can use the same kind of PSU from T1 for Orpheus (with lower voltage of course)? I think so, but it could be very expensive mistake if I am wrong ... Any advice? http://farm3.staticflickr.com/2891/9135996783_0911380a26_o.jpg

Hello, Just joined here. I am not sure if i used the search function correctly, but it showed nothing for either the FUN or HDP. Will anybody give some recommendation or comparison between the FUN and HDP? Thanks

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?

While my K340's sound produces an instant grin even when powered from my mini-dac 1/4" output. I am looking now for an amp so that can let the K340's sing My initial budget is $300-$500 (used or new) I'll be feeding the amp from XLR out's of my apogee mini-dac.

Anyone have any good combos they would like to recommend? Currently using Russian 6N6P as driver and Sylvania 6922 as output and a EZ80 in the power supply

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?

everything considered should be under $150... preferably under $100 to buy or build. some amps of up to $300 in cost to build or buy may be considered if TRULLY worth the extra dough... but try to keep the recomendations under the first list of requirements. also, list what phones and IEMs the amps pair well with.

Didn't find an existing thread for this amp, so I thought I'd start one. I spent the last week listening to one I had on loan from TTVJ and compared it to the FET-A, also on loan. The following is sort of my "mini-review" of the P200 to share my impressions. Disclaimer: these impressions are based on 6 days of listening, far from ideal. Normally I would've liked to spend at least a week per headphone which is what I've done in the past, so even I might disagree with my own impressions later. My opinions varied a few times during listening in fact and without enough time to confirm what I heard via repeated listening, take these impressions with an extremely small grain…

Hi, Newbie here. I bought a pair of Stax SR-404 Signature and want to build an energizer/amp myself. I'm not a big tube fan, although I can see the value in using them. Instead, I'd like to build a fairly compact solid-state version. Does anyone have any links or references to interesting designs? Thx D.

Somebody save this guy. Anyone who flies an airplane should be concerned about fires.

I got a quickie HF-style poll for y'all. Got me some HF2s and AD2000s, and I'm looking for a cheap, temporary amp about $200ish. I'm probably gonna have a chance to buy one of these soon. I don't care for amp coloration; I just want my source and phones to do their thing. The amp just provides the power and keeps the signal clean. Other suggestions welcome, preferably used and available right now. Edit: Oh yeah, and impressions/comparisons are very welcome. Thanks.

http://vivaaudio.com/en/products/egoista-stx/ Came across this amp, anyone know of it or heard it?

But have you ever recommended an amp not sold by cattylink?

Anyone here has one of these singlepower solid state amps around? I know they were made in a balanced configuration? I remember at some point there were a few units around

Each time I hear sacd lover's MPX, or Edipus's PPX Slam, I reall like them. But I pretty committed to not getting a tube amp because I pretty much don't want the tweakability a tube amp provides -- switching tubes, spending lots of money on NOS tubes, not being able to find tubes that sound exactly like what you had before, etc. I just know it would drive me a bit nuts. So.... Does Singlepower have plans or has it ever considered making a solid state amp?

What is the story on the "cryovalve" process? Quote from Tube Depot CryoValve Story:

Anyone get a chance to listen to the Peachtree Grand pieces at RMAF (or elsewhere)? I'm looking for a dac/amp that'll do 24/192 over USB and this appears to be a contender. The design intrigues me because it permits user selectable signal routing via tubes or SS. I'm open to other hardware suggestions for a solution to 24/192 over USB. Trying to hold the line at $5K USD Peachtree Grand Integrated High resolution DAC ESS Sabre32 9018 - supports 24/192 asynchronous USB input Hybrid tube preamplifier - uses two 12AU7s High efficiency amplifier - 400 wpc stereo Galvanic Isolation State of the art headphone amp - signal is run through the tube stage [no mW spe…

http://www.6moons.com/audioreviews/eddiecurrent/ec01.html This is an outstanding review for the EC-01. It is very well written and votes very well for EddieCurrent.

So, this is coming out in a week. As I'm busy trying to learn about such things, I'm curious as to why someone would choose to build a Class D portable amp, or if it's such a good idea, why, with the explosion of portables, hasn't it been done more (I think Headroom has a Class D desktop, but I don't know of others)? http://www.i-qube.nl/index.php?id=18 EDIT: I'm thinking mainly in terms of sound.

I'm interested in building the Stax Transformer project here: the STAX Transformer as it seems relatively easy to build but I've searched everywhere I can think of but can't find any reviews on this beast. Has anyone built this project or know of any reviews detailing performance, SQ etc? Tim

I have had my HeadAmp Gilmore Lite + DPS for over three years now, and I have never given serious thought to replacing it. It drives all my cans to a satisfactory level, except of course the TakeTs. Earlier this year I had designs on going balanced, but four months of house renovation has ensured I won't be bankrolling that any time ...ever, really. I'm now content to live in the single ended solid state world, but.. I am in need of an amp with more than one input. In spite of my recently acquisition of a Quad 99 CDP-2, and its variable outputs, I could benefit from the GS-1's preamp outputs as well. I see a lot of Beta22s changing hands around here. Most are mad…

Hi, Check this 12000 euro amp out. There are so many $10k amps popping out these years. They come from workshops. Actually, I doubt if they are really worth the price. (I am only able to upload 3 pics.) Angstrom Audio Laboratories is back at it again with a statement level Headphone Amplifier of uncompromising standards. MSRP $13,750.

... I don't have the amp! Lol!! First of all, hi to all As I reported in the Title, I've already a vintage rs-1 recabled apuresound V3 and a Bluenote Stibber as cd-player. But I don't have the amp, I would like to recive some suggestions. I'm thinking of some valve amp in the price range of 1000euro/1500dollars, no more . I'm thinking also about the earmax SE, what do you think about? I've already possessed a rudistor nx-01 and nx-33ev08! For now thanks a lot! Marco

Got an email from Todd @ TTVJ, he has this for pre-order, looks interesting with a Korg "NuTube" triode.... http://www.ttvjaudio.com/Apex_HiFi_Sangaku_Headphone_Amp_and_Pre_Amplifier_p/aaa0000998.htm http://www.apexhifi.com/Sangaku.htm
