“ I recently had the opportunity to listen to WA6SE on demo for 2 hours at the comfort of my home and this is my take on it. The DAC is DACport and the headphone used is LCD-2 Rev 2 if anyone is interested to know. The actual amp consists of 2 separate units; one is the actual tube amp while the second unit is a separate power supply to the amp. The 2 units would then be connected via a...” --Joe-Siow
“ I'm a relative newbie to the headphone game. My reference system (at the time of writing) is a Burson 160D, and having a good reference is essential when you're comparing tubes. My reference headphone (at the time of writing) is the Sennheiser HD 650, which are known for their veil until you put great amplification with them. I also own UERMs, which aren't...” --reeltime

“ This is not a full review, just a rating and a few comments. I bought my WA2 used, and was really surprised how good it is. The WA2 is among the better headphone amps available.

The WA2 has some pretty impressive power delivery, and it works wonders with high-impedance cans like the Beyerdynamic T1, and is also...” --Skylab

So how does the selection process work? The big question is which amplifier to have these guys make for you, and why? I have had tube equipment forever. My first...” --Redcarmoose
Energizer for Stax pro-biased electrostatic headphones.
“ I had the WA3 in about 2005. It was a great amp with my Senns... not so much with my Grados. It had all the great sound qualities of a fine OTL tube amp, especially with the Tung Sol 5998 / 7236 rectifier. Anyone would be very pleased with the WA3 / WA3+ to drive their high impedence phones - but, I'd rather have a tube hybrid, or TC tube amp to drive my Grados / Denons /...” --Gradofan2

“A Tale of Two Tube Amps Woo Audio WA7 and ALO Audio PanAm My normal gear preference and choice for many years has been solid state. I have held a curiosity, however, in tube-based audio gear and the possibilities and presentation that comes from it. It might be considered ironic that considering how endlessly I have been fiddling with my main system for years now...” --Currawong
