Did some listening with very nice DIY preamp. Tonalities sounded great, less warm but not sterile; music had a presence but not that same kind of intimacy from tubes. A different kind of intimacy -- an immediacy, more like it. Soundstage depth was pretty much gone, and width was ok but not great for some tunes where tube amps pull things nicely apart a bit in the center. This pre is dead quiet, so that's a plus.
Every pre will be different, I know. But I have to say that what I'm hearing from this preamp, if it's even a little typical, won't make me want to spend too much on a pre. Now, I'm sure that other SS pre's are different and maybe better, so I'm not closing the door. But so far, the best thing about it compared to tube preamps is not having to turn off the power.
