Thinking of changing my solid state pre amp

Really tough question, so I have a few to help others chime in:
What type of music do you listen to?
How loud do you listen? 
What other gear will go along with the pre? (amp/speakers etc)
What is your budget? 

I didn't mention this in the 3 that I posted, but actually the Conrad-Johnson Premier 18LS is an excellent pre, I have seen it once or twice below $1000.  All the models that I have listed are excellent performers and will do a great job with your 2550 & Totems, 
Good Luck with your search.
