I've had the 2X150VT for about a month now, and I'm loving it. Driving Magnepan 1.6. Quite a powerhouse too. It replaced a Jolida SJ 801 integrated. Before that, Krell, Classe.
The Smart is the best for me so far-not cool and bright, not too warm and fuzzy either. It ain't the perfect solution under $2500 I'm sure, but I think it has a great sound with my tube preamp, and the price was right, if not a downright bargain.
A couple of nitpicks- the power switch is cheap feeling, and has a too bright orange light, also the speaker binding posts could be better, and spaced further apart.
