I have a surround sound system Based around an Arcam AVR 390 and KEF Q150 speakers. I absolutely love listening to Stereo music on this system! I am trying to create a system with similar sound quality for my home office. This only needs to be a stereo amp not an AVR. What recommendations would people have for a system (amp plus speakers) for a budget of $500... is that possible? If not, I’d still be interested in recommendations that help me get a sound quality perhaps approaches what I get from my “main” system.
