tube amp

I unexpectedly got my hands on this interesting unit. It's a guitar amplifier, but it has no preamp so it should technically be a simple tube amp. Since it has two channels it can technically be used as a stereo home audio amplifier. If that would make sense and how it compares to actual 'hifi'...

I’m currently using an Yamaha RN-1000A, it sounds okay, but overall I’m not really happy with it. I cant really customize anything, like frequency etc. YPAO sounds bad, the rest is okay.. And it just has so many ports for other stuff that i won’t use. For me I just want an simple amp, simple...

After building my first tube amp (https://www.audiosciencereview.com/forum/index.php?threads/building-a-valve-amplifier.29903/ ; https://www.audiosciencereview.com/forum/index.php?threads/hpa-glow-one-diy-kt88-amplifier.39332/#post-1468245 ) a friend of mine listened to it and said he wanted it...

In Stereophile's review of the Mastersound 845 Compact integrated amplifier, which is a tube amp, editor in chief Jim Austin is once again publicly disagreeing with a reviewer; this time it's John Atkinson. Basically, the TL;DR is that in the measurements section of the review, Atkinson (JA1)...

Hello everyone, I am a vintage audio enthusiast who enjoys designing, modifying, and repairing tube amplifiers. I'm also an objectivist and a long-time reader of ASR, but I've always wished there was more tube-related objectivist content on this forum. As we all know, tube amplifiers are far...

Hello, I have Darkvoice 336 SE tube amp connected to DT 1990 PRO and that I use all the time and I wanted to try some different tubes than my old trusty Sylvania 6SN7 GTB E6B ones so I bought one KenRad 6SN7GT (pricey little thing) and two PSVANE UK-6SN7 (ordered one but arrived as pair) KenRad...

One of my next projects is a valve amplifier. I built many solid state amplifiers and I'm very happy with these. I always considered valve amplifiers as being vastly inferior to solid state one but nevertheless I would like to build one to measure it and to listen to it. From all the available...

SS vs. tube amp for Senn HD 600? In all my years of research, mostly using the Head-Fi forum, HD 600 has been said to sound best/synergize with tube amps. But I get the impression here (or maybe Reddit? memory is fuzzy) that SS is always superior, at least in my price range, which is $100 -...

It was about 10 years ago that I bought a pair of Grado 225's and I thought it was a real big deal. The local shops here in Chicago push Grado hard, they looked cool, and they fit the budget. I think at the time I purchased a little Fiio amp to go with it, and I was as happy as could be...

Right now I'm in the market for a Stax SR-009(S) and I'm in the search for an amplifier to go with it. My issue is there are a lot of tube (valve)-based ones, and this is a deal-breaker for me. I'm not assuming those valve amplifiers measure bad (we just don't know), I just do not like valves...

I recently discovered a hybrid amplifier called thda 500t v.2 made by a company called Taga Harmony costing about 315 dollars for that money it has a lot of features but i wonder if it just might be a bit to good to be true... i have never tried tubes before and thought it might be fun to...

I'm preparing to unload my last piece of Schiit - a Gen 1 Schiit Lyr. It's a tube hybrid, for those of you who have not been mired in Schiit. It's not terrible, as far as I can tell, but I have zero faith in anything designed and manufactured by Schiit. So time to go. So, what should I buy...
