I’m 100% satisfied with my purchase. It has been everything that I hoped it would be. Very well built, and certainly a conversation starter. But the sound is where the magic is, warm and natural.

WA22

I absolutely love the WA22 right out of the box. I haven't rolled any tubes and it already sounds excellent. I honestly like looking at it just as much as listening! Lol. It is beautiful and heavy which I like because it feels very well built. The sound is full but not bloated. Dynamic but not too in your face! Detailed but still musical! I also love the sound of the WA22 preamp out to my Soloist GT! Injecting that tube sound with solid state is really nice with the Arya and lcd x. I prefer my Verite Closed on just the WA22. I had never heard tubes and I bought this without hearing it. I am soooo glad I did. The Soloist GT is $2500 amp that is very very good but there is just something about my the WA22 that gives my music more emotion! I am listening to music I never really did before, my sessions are much longer, and I am discovering that tubes are definitely my preferred way to listen.
