pre and amp ideas 10-12K Budget

Currently I've been on a mission to upgrade my system. Currently I have a modest system consisting of:
Pre- Golden Tube Audio SEP-1
Amp- Adcom 5802
CDP-Esoteric DV-50
Turntable-VPI Classic
Phono pre-Jolida JD9 (doing mods)
Cables AVT series by MIT
Speakers-Carver Amazing Silvers

Not to long ago I asked about Pass and Bat. Biggest problem I have with this is there are no places for me to demo gear, etc any where local to where I'm located. The only BAT dealer nearby (over 2 hours away) is still a dealer but doesn't carry anything. next cloest is about 5 hours. I know hearing something at a dealer isn't the same at home, I understand that. But I would like to hear SOMETHING by them to at least get a feel for what the overall sound is like on them etc. I also haven't had a chance to hear anything by them and really want to make an educated purchase than just oh that looks good on paper type buy.

Right now I know I'm making a big jump in gear and I understand that. I wanted to move from more entry level gear (for pre and amp) to something higher up the chain. I would most likely buy used however want some suggestions of what I should look for in this price range.

If someone feels that I would also be better suited by changing on the speakers let me know. I'm trying to grow and learn. I started out in HT about a year ago and only been into 2 channel for about 6 months. I find that I love music more than HT and really haven't done much on that front for awhile.

Overall the sound I like is very dynamic and deep controled bass, very punchy and tight no flop. I also find I enjoy detail, making sure I can hear everything thats there and not having something covered up in the track. I mostly listen to rock, small group jazz, and folk.
