For what it is worth, I tried a Pass X350 with my Primia Luna Dialogue Premium and thought is sounded good, if a bit polite for my taste.
Preamp upgrade opinion...
thinking of upgrading from a Levinson No. 28 preamp w/phono to something else. I currently own a Pass Labs x250 amp and my musical tastes range from rock to reggae with an occasional jazz piece. I'm not certain a tube preamp would fit the bill (please correct me if I am wrong!!!). Currently use XLR inputs and outputs in my current setup and could probably go with RCA's if need be with a future preamp. What could I possibly purchase in the <3k market with something a little newer. The phono option would be nice but not mandatory. Let's discus. Regards. J~
