Indeed the Adcom should be upgraded. A quick band aid solution which is not cheap, is to use Cardas Golden anything interconnects.
There is something about that Cardas Copper or geometry that really helps mellow the sound without losing detailed information. IF you can't get the Golden Refs for instance, try some other Cardas Golden Q geometry cables but avoid the neutral refs, or the clears. You want the warmth that Cardas can sometimes give a system's overall sound.
Or buy a good tube power or integrated amp. The value these days is in Cayin or Prima Luna. Buy used if possible to make it affordable.
