What kind of sound do you want? I recommend choosing speakers first, then optimize electronics to support your speakers.
I realized after 35 or 40 years that I really wanted a system that made all music genera sound good and that acoustic music sounded like acoustic music. I found Sonus Faber speakers and Audio Research for electronics… then the higher level in each the better, more musical and detailed each upgrade put me. Very happy now. Sonus Faber speakers: 1) Cremona, 2) Olympica, and finally 3) Amati Traditional.
