“ the woo wa6 is the single-chassis smaller sibling of the wa6se. but don't think for a moment that listening to the wa6 you'll be "slumming it". not at all. because, the wa6 is, quite simply, a wonderful amp. from the tank-like build quality, to the sexy anodized brushed aluminum finish, to the amp topology, everything is top notch. and the sound is great in all...” --TheWuss
“ Takes the edge off the Sennheiser HD800's thereby matching up well with them. Great separation, silent background and low fatigue factor. Not much to say that hasn't already been said before. Very nice little tube amp. ” --RavenDog
“ 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

It actually surprises me that it's not even more popular than it is. The WA2 has some pretty impressive power delivery, and it works wonders with high-impedance cans like the Beyerdynamic T1, and is also...” --Skylab
“ Product Standard Build Woo Audio 5 LE Headphone Amplifier In this day of mass produced equipment it is nice to find a small boutique headphone and headphone amplifier company who are sincerely into it. 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
“ 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
