I’m surprised at the lack of focus on the relationship between the preamp and the amp. In my experience, the electrical characteristics of the preamp’s output and the amp’s input has had the greatest influence on getting good SQ out of the match.
That of course assumes decent gear. But I would bet a lot of what people are hearing and experiencing isn’t really inherent in the preamp, but rather the combination with the power amp. Lesser but still true with the relationship between the source and the preamp - my phono stage has a hot output and some of the preamps simply haven’t like it. It's a bad match with my Levinson.
In terms of SS, I have a Bryston, a classic Levinson ML-26, and an Emotiva. I use the last one the most, for daily low volume listening, because it has more true balanced connections that I find easy to switch around, but clearly the Levinson sounds best for focused listening. When I really want to rock out, I’ll go for the tube BAT preamp as I am loving the old stock tubes I’ve rolled into it.
