It's taken me 2-3 years to put together this system. I consider it a baseline from which to try other components. Prior to this, I didn't feel I had enough realism, detail or musicality to begin to properly evaluate equipment. I don't listen at high SPL's and value most the accurate reproduction of piano, guitar, violin, cello and human voice. Along those lines, I'm very open to suggestions for improvement. I've mainly been working on room treatment lately.
