    Best practices when using OTL tube amps?

    First time poster here. I recently purchased an entry-level OTL tube amp (an Xduoo TA-26s) along with some upgraded tubes, and I'm looking forward to giving them a try. I'm having some trouble, however, finding clear answers to some basic questions regarding "best practices" when using an OTL...

    Xduoo mt 604, tube amp contact problem

    My xduoo mt-604 has some contact problem, it is slight. Would a non-audiophile overlook it? Sure. It's in the left channel that depending on how you move the 4.4 and xlr output, you lose some frequencies. It also happens if you move the valves slightly. This drove me crazy to the point that I...

    WA2 OTL Tube Amplifier Noise (SOLVED: Problem With Defective Power Tubes)

    Hello everyone! I hope you are well. I purchased this amplifier used, have demoed and this was the setup used. HD800S -> Amp -> DAC (Chord Qutest) -> computer, which made it have zero noise whatsoever. Regardless of me changing the volume rapidly (which does create noise on my setup.) Whenever...

    What are your favorite Tube AMPs?

    I've been curious about Tube AMPs for a bit and I've decided I want to invest $1000 in one. So far I'm looking at the Woo Audio WA7 Gen 3 & the Feliks Audio ECHO 2. I'll be using the Focal Clear MG as my main and from time to time I'll switch to the HD800s.

    Tube amps (or dac/amps) under 1000$?

    What are your recommendations regarding headphone tube amps (or dac/amp) under 1000$? Do you think they are worth the price for sound improvements over a cheap Little Dot MK2 with Voshkod tubes?

    Is there a list somewhere of existing DIY headphone amp plans?

    I’m interested in possibly building my own tube amp. It doesn’t need to be very powerful since my headphones are very easy to drive but it needs to have a big tube sound. Maybe something with a 300b but not necessarily. Preferably something that isn’t hideous. Preferably would like too keep...

    Amp (tube?) recommendation for Quad Era 1?

    I know that most don't recommend tube amps for planar magnetics, but Quad specifically made a tube amp for the Era 1 and I am wondering if anyone has a tube (or other amp) recommendation for this set that doesn't cost an insane amount. I am currently running a modi-magni, but my magni has an...

    Help me choose my first tube amp and DAC?

    I want to buy my first desktop tube amp. The thing is, I don't have a dedicated DAC so I'll need to get one of those too. I'd like to spend about $600-700. I was looking at the xDuoo TA-30 Tube AMP/Dac combo for $600. It looks like it might be a great choice, although it's a little obscure. I...
