Thanks, Verdant, for your reply. What I'm looking for in terms of sound is clarity and precision in midrange with adequate and accurate punch in bass. It's ok for it not to rattle the furniture, I just want to be convinced that a jazz upright bass sounds like itself. I'm a middle-aged guy, so I have no illusions about what I can hear, but I want good staging.
My Adcom is from roughly 1993 or so. It has not had any work done. I'm not sure what I'd be asking someone to do. Advice appreciated and some sense of what it might cost.
Thanks for the amp details and turntable suggestions!
I have not sold my CDs, luckily, but it would mean a lot of re-ripping. Oh, and I need a disc ripper, now that my Macs don't have them anymore. (Oh, technology, I love you and yet you make so much trouble.) Perhaps I just go the subscription route. I listen to Spotify all the time, anyway.
