Spetula, I'm not familiar off hand with the sound of the Infinitys you have currently. Are you changing them?
As for preamps, you can do a lot of things for 2 channel.
If you want to do solid state preamps, my experience(besides doing passive preamps like Pass L/P,McCormack TLC,etc) is that you'll have to spend some bucks to get a great high end solid state with some dynamics and refinement. You'll get much better deals on used TUBE PREAMPS that will sound excellent(beating up on any preamp section in an AV pre/pro) in the $400-$2k range. Anything from Golden Tube SEP1(cheap), Audio Research LS2/LS7/LS5/LS22/Ls16, Sonic Frontiers L-2/L-3/Line-2, Audible Illusiones Mod 3a, Copeland(excellent for $!!!), Any CAT preamp(excellent high end!), and I'm sure a lot of the CJ stuff or BAT can be worth a try if the price is right. Never the less, the choices are endless!
You really might read some reviews and give one a try...you can always sell it if you want to move on..
Good luck
