I must say, the WA6 is pleasing me very, very much for the little amount of time I've had/listened to it. I've actually never heard my music this way, the separation and the texture of the music is just…well like I said, something I've never heard before with another amp. I've also never heard sub bass like I'm hearing (very subtle) not overwhelming at all and the mids and highs seem spot on for me, and the sound stage is very nice, but still very focused and clear, where I'm able to hear instrument separation in places I've never heard (sounds instruments are outside of my head in the high/low-left/right- front/back and center, if that makes any sense). Also this amp delivers that Grado sound that makes me love Grado, still has that somewhat of attack, but laid back just the right amount, for me. After having the Ear+HD for the short time I had it, I was thinking to myself maybe I'm not a tube kind of guy when switching from my Adcom-710 (which is lightening quick and sharp), and then hearing the Ear+HD (which was very smooth and mellow), I sought of missed that quickness of the SS, but at the same time liked the smoothness and the warmth of the Ear+HD. With the WA6, I find it is falling inbetween both of these amps, and more... much more than I ever expected! I know i'm being quick to say this in such little time, but I may be done!!!
Congratulations. Always nice to hear of someone finding the magic in tubes and WooAudio.
