recommendation of amps

Just looking for a little guidance. Starting to look for an AMP.  Most likely solid state. I listen to R&R only, high 80's low 90's    Room 13x14 bathroom to one side hallway to another, normal furnishings, wood floors.  Speakers, Fritz carbon 7se bookshelf, SVS SB3000 Sub, Currently Peachtree amp 500 running system (not Bad)  Benchmark Dac 3B and LA-4 Benchmark Line Amp, Audiolab 6000 CD Transport, Everything Balanced, with the exception of the Transport. Stream Qobuz also. System sounds really good. Just looking for a TOP SHELF AMP.  Budget maybe 6-7 k new or used, (Less preferred)  Prefer new with warranty???  Have a ATI AMP 6002 in main system, in another room, much bigger room, and kicks ass, in every regard. Would like something different (maybe)  Current set up feels a little neutral, and analytical,   maybe looking for something a little warmer.  Have been looking at a used Pass Labs 250.8  for example     Maybe a little overkill though? Always a little nervous over tubes (scared even) Afraid of NOT ENOUGH JUICE to listen at my levels.  Very open to your suggestions. Thanks as always     Robert TN
