ProAC 2.5 users please share experience on amp

Sorry I have to start a new thread again about right amplifer for the proAC response 2.5. I am searching a good match for it. Please share your experience on this. I am using Cary SLI-80 sig currently. Sound is beautiful but think there maybe lots of space for further improvment. Based on my researh here:

SS: Plinius 9200

TUBE:
Audio Research (VT100+ LS7)or VT50+ LS7
C-J premier 11a or 12

Pretube/SS Power:
Blue circle BC21/BC22(or BAT 200)

......
anymore input? I listen to classic and some jazz.
the budget is below ~$2500. room size: 16x13x9 . I prefer to tube sound~

Thanks in advance~`
