[The WA2] has iron-fisted control of any headphone I throw at it, and most importantly – it communicates with me and my emotions.
WA2 is one of the most musically involving amplifiers I have heard, and for the price, awfully close to the state-of-the-art - Enjoy The Music.
WA2 has a superb ability to render harmonics and acoustics. I feel like I hear more of the overtones of acoustical instruments, which produces a richer sound, but more importantly, they sound more like the same instruments sound in real life in a real space.
If we had to pick a single word to describe the Woo Audio experience, it would be 'luscious' -- deep, smooth bass, rich vocal reproduction, and a sweet, spacious, notably airy treble that's smashing for live classical performances - CNET U.K.
I heard this amp at the National meet and it is a winner. It rocked with RS-1s amd makes a great preamp as well. - By jp from head-fi.org
Let me tell you that the WA2, armed with the Tung-Sol 5998s, is one imposing through wonderfully elegant statement product that conveys quality long before you plug in your first set of cans. I could not help but sit in my chair and admire the look of this product...I loved the sound of this recording on the WA2 with stock tubes on my AKG K701s. The trumpets and sax featured an open, airy and enveloping property that I found to be entralling. Highs were well defined and clear, without being over powering.
