Advice / Counsel re: Upgading System


I would like to upgade my system to the next level, but don't have much direction as to what to do next. I live in a rural area with no high end audio dealers near. Current system is all Adcom; GFA5800 amp, GFP750 preamp, CGD750 CD and B&W 801 S2 Anniversary speakers. I love the sound, but want to go to the next level. Wondering about Levinson, Krell, AudioResearch, or ?? but would be acquiring pre-owned, not new. Any advice, things to consider, etc. appreciated. Thanks in advance!

B&W bought Classe to provide "companion" electronics for their speakers. Now, I mention that as a starting point. I suggest a slush fund to begin purchasing and listening to equipment that you can "turnover" without suffering to much of a loss until you find that something that meets your criteria. Let your ears decide. Just a thought. Good luck.
Small room will require smaller speakers I'm thinking.Hard for those to breathe in a 15x15.You have 100's of combo's with your $$$$....its a good feeling when you got it going,good luck,Bob
