Sorry avdweeb--
been a while. I haven’t heard the AVA components and, although I’ve heard Prima Luna at shows, it was not at length and not enough to form an opinion. I would say that if you pair the Wells up with a nice tube preamp, you will not be disappointed. I’ve heard it with high end solid state and tubes and it is unfailingly musical. The tube front will give it more dimensionality and liquidity. I liked it so much with the tube pre that I thought the system was all tube with exceptional grip.
No problem! I'm still struggling with this decision, and am trying to pin down my thoughts over here:
