I own an Esoteric A-03 amp and C-03 preamp. As with true Hi-End electronics like (Esoteric) they don’t call attention to themselves. If you want more coloration to your music Accuphase is a great choice. IMO to put a true Hi-End system together is find the most neutral and transparent electronics with synergy you can afford and let the most flawed component(speaker) determine the amount of coloration desired.
