I don't have a cart recommendation, but I'm not sure I'd choose the Bellari as a means to try tubes. It doesn't behave any differently than a ss phono IMHO, is a little temperamental (noise/grounding issues) and I think overpriced frankly. I had one and thought it was a decent phone pre, but don't understand the hype. If you need a phono pre, compare it to others in the price range and pick the one you like. If you really want to try tubes, I'd try a tube preamp or line stage, or power amp. You can do this for only a little more $ commitment than the Bellari.
. . . just my 2 cents.
