Headphone Amplification

Well my new SinglePower amp arrived today. It has two gain stages and uses some nice powerful tubes as the output tubes. Here's a bunch of pics:

Has anyone an ideal as to when this unit will come out and an estimate for it's price? Thanks

The more I think about, the more I realize that I don't really want an Omega 2 setup, and all the RS-1 loving has really got to me, so now my target is on a RS-1 setup. I'm set on getting a Singlepower amp to mate with the RS-1s, so this thread is to get some good info. 1) I'm going to get a MPX3 as the base, with octal tube sockets for maximum flexibility. 2) Gain tube: So far I know you can use the 6SN7, 7n7, 7af7, and their 12/14v variants. I'm a bit wary of using the 6SN7 since good NOS 6SN7 are expensive as hell. And also, what does the 12v option do to the sound? If I get it, does that mean I can no longer use the 6v variants? 3) Output: I'm pretty much set on…

This is a long time coming, but with the corona virus, I've finally got time to do this. This is my review of the KGSSHV Carbon I had commissioned from @joehpj (thanks!). I've purchased a pair of Stax L300 Limited to replace the Stax Lambda Pros I had been using for some 25 years before Hurricane Harvey flooded my house and destroyed my old headphones. I've upgraded the pads on the L300 with L700 pads--these make a noticeable difference for me, as the thicker pads allow me to get a decent seal even when I wear headphones. I've been driving them with a Stax SRM-252s, and it has become apparent to me that the amp was the weak link in the chain. After seeing photos …

So, I just ordered a FirstWatt F1 for my K1000s, and I'm getting that feeling that you get when you get new toys WHEEE

So I need to send in my Balanced Desktop for a minor repair. I am very tempted to have them install a stepper while it's in the shop. Yea or Nay?

This has got to be a misplaced decimal or something http://www.ebay.com/itm/331996665716?ul_noapp=true

Okay, I've been debating streamlining a bit if not downright downsizing. I find that I don't use "multiple" amps and sources nearly enough to justify having them sitting around so I'm thinking about a move to get a single amp that can handle various needs. Right now, I'm using nothing but headphones but likely will be adding speakers somewhere down the road plus I'd like to try the K1000 sometime. With that in mind, should I part with my MPX3 slam and GCHA and just pick up something that's a bit more flexible? Say the SLI-80 Signature F-1? It seems to fit the bill and from what I've read it's a solid performer with no real weaknesses. So the question.....go for it or s…

I'm about to buy a pair of 6bx7gt's for my old skool toaster MPX3. First of all, will it's psu even be able to handle them? Second, what are some good ones? I'm probably gonna buy them matched from tubeworld.com, if there's a better dealer that takes paypal tell me! Would you recommend the "O" or "D" getter halo tubes? And what brands? They seem to recommend the GE branded amperex and RCA tubes, but then again they're selling them...

Taking a hard look at the Qinpu Q2 from Head Direct. Exposing my noobness but WFC's so... Will this power Absolute Zero Speakers satisfactorily? Anyone have experience with this? Anything else I should consider in that price range $79 ($99 Shipped)?

I'm about to get a tube headphone amp that uses a pair of 300B tubes and am looking for any recommendations on reasonably priced tubes (under $300 / pair). I'm thinking about getting the JJ Tesla, but would like to hear any other recommendations on 300B tubes. Thanks, Steve

I just got a Dynahi and the amp makes a pretty loud sound when it turns off. Can this damage the headphones? The other option is to unplug the headphones and short the amp to ground, which can only be a terrible idea on an amp this powerful.

Has anyone here heard a Woo 3 with top of the line super duper exotic tubes? I'm just wondering how it would compare to something like a singlepower. It would be alot more convinient for me because of the size, but I don't want to lose out on SQ. By the same token, how about an Earmax?

I've read some rather interesting comments over the past year or so regarding the DarkVoice. Is it something like the Ming Da and Bada offerings (relatively not so good in my opinion but some are quite vocal about it), or is it actually pretty good? Would anyone take it over a PPX3 SLAM? What about the Dodge amp some other people (you know who) are pushing?

I cant wait! Should be here this afternoon when I get back.... Its going to be a long few hours...

i have recently bought a DT 990/600 and now im looking for amp. but will amp be enough to get a great sound for 40% music 40% gaming 20% movies i heard some people suggest getting both DAC and AMP. i'm going to use them on my gaming laptop but i do not have a good sound card(realtek HD). For the amp im leaning to MK III with M8100/CV4010 im new to setting these up

I felt really bad hijacking humanflyz thread so I've created this seperately. I've done plenty of searching at the other place. Earl one of your posts from Headfi. Just doing some searching for uber Grado amps. I'm convinced the 6BL7GT/A is the way (if this will provide tons of current for the Grados) I want to go, unless there is a more high current tube that can be stuck in the MPX3 without driving the costs to Supra levels. Out of everything I'm looking for in a tube amp bass slam, and bass control is probably the most important thing for me. I'd like tight controlled bass with excellent attack and decay. And uh...don't mess with the Grado midrange too m…

I just got an SRM-T1 (my first Stax amp) to go with 404LE (my first Stax headphones). I see there is an earthing terminal. Under what circumstances should I use this, and how should I use it? (Balanced cable specially made up?) TIA Nic

Hello all! I'm looking for a decent but cheapish DAC/Amp that has significant negative gain, and was wondering if anyone knew of anything? I'm using it to connect to my digital piano software, with which I use a pair of Etymotic 4XRs. At standard levels and 0dB gain I usually need to attenuate by at least 24dB before I can even get close to half volume with most pots. I'll add that I'm also using it at relatively low output levels because of my messed up ears, so it really would be nice to have some meaningful volume range without having to use massive digital attenuation. Also, using that kind of digital attenuation still leaves the amp itself at a much higher outpu…

I don't know if there is anybody that has heard both of these amps, but if you have, which one did you like better. And if you haven't but know a lot about tube amp design, which one is better designed / made? I'm looking for the best possible amp for both the K1000 and the HD800 and now that I am leaning towards a tube amp, these two seem to be the leading candidates. Unfortunately, I know nothing about tubes or tube amps. (p.s. let's put aside the fact that Eddie Current is also balanced since (a) it doesn't matter for the K1000 and ( while I may buy a balanced cable for the HD800, I likely won't be reterminating other headphones with hardwired cables.)

I was skimming some hi-fi magazine this weekend and I noticed the announcement of this product. Teddy Pardo is mostly known for his aftermarket power supplies for Naim products. Does anybody have experience with this amp or his other boxes? There's very little useful info on the product page (e.g., gain or power), and no reviews yet.

Would there any electrical issues with using my old-chassis SDS as a preamp in my speaker rig? As I splurged on the speakers and power amp, I'm not immediately going to have the funds for a high quality dedicated preamp. The SDS doesn't have RCA outputs, so I've been using a 1/4" -> RCA Y cable from the headphone output. My current SS monoblocks have an input impedance of 33K, the new tube monos I have on the way will be 100K. Would the output impedance of the SDS be a concern for preamp duties? I've got the 5687 output tubes in my SDS; can I assume those will be better than the 6sn7 for preamp use as well? I have briefly tried this (lesson learned - keep volume at …

For some reason which I can't explain, I wandered over to the Cavilli website today and saw that the Liquid Lightning 2T was selling for $2499.50. Original price was $4250. Wonder what's going on?
