First - put a good power cord on it, I mean good not $100 something.
If it is new, the cord, give it at least 300 hours of burn-in time.
Second, or at the same time - put good interconnects on it, the same company as the power cord, the higher in line the better, 200 hours burn-in time.
This amp should not sound bright.
I would probably try Audio Art Classic interconnects, $100, and power cord, $150- $350. The Classic is a very good cable, I just tried it. Don’t expect too much from it though, but it is quite clear and balanced.
