For me, the WA2 is a superb headphone amp, and an OK-but-nothing-more preamp. As a headphone amp, it drives my T1s beautifully. As a preamp, it creates a rather diffuse soundstage, and is a bit too loose in lower frequencies, and a bit noisy. Maybe this is due to the particular tubes, maybe to the interaction between the Woo and my amp -- in other words, for other users driving other amps, the WA2 might perform very well as a preamp. I'm content to appreciate it as an exceptionally fine headphone amp.
