“It is transparent, particularly in that you don’t notice any treble veiling or grit as you
do with some lesser headphone amps. Bass is solid, well defined and can be very deep
with the right headphones. Tonal balance is very, very good, with no sense of treble
roll-off or brightness.” – Playback, issue 43
“Woo 22 balanced headphone amp which, with the premium tube upgrades, presents
the most effortless, immediate presentation of sound I have heard from any headphone
system, or perhaps any stereo system.” – Positive Feedback, issue 54
“The Sennheiser HD800 headphones and the Woo Audio WA22 integrated headphone
amp configured in fully balanced configuration is one of the best audio systems I have
heard. Tremble and midrange performance are as good or better than any headphone
or two-channel standalone system I have experienced. Bass is very satisfying and will
only be bettered by the very best fullrange speaker and subwoofer systems.” –

“I have since tried HD 800’s with the prototype Woo Audio WA 22 amp (which is tube
rather than solid state amp that has variable output impedance). The WA 22 takes the
sense of vividness up a notch, mostly by making the midrange contrast level higher,
while introducing minimal if any deleterious side effects. The mostly subtractive errors
noted above are still there, but they are diminished in the overall presentation. This
gets me to the level of really, really liking the HD 800s. The HD 800s are so good that I
could easily live with them over the long haul. (page 115).” – Playback Guide to
