In the area of say US$1K, I am looking at DAC/AMP Combos from primarily Schitt and Woo. Naturally, Schitt has the most combo offerings. With Woo I am limited to the WA7 w/ dac or the WA3 + a DAC. Anyone care to comment about sound and reliability of either brand? I like the idea of future proof and 5 yr warranty from Schitt, however the WA7 gets such good reviews. What say you?
