DSP maybe...but the potential for 'brightishness' could still be apparent...esp. if one has lived with the equipment for awhile....'closeness' can breed contempt as well as affection....*s*
Digital eq's are pretty quiet, and some can be very precise is used with a DSP with a light touch... When I 'hear' "bright in a comment,; I think 'crisp', but that's what I prefer. Overall, 'flat' is my average 'D2D'.
HO: Speakers. Amp is what 'processes' the signal, the speaker recreates.
Moral: DSP+eq might 'damp', but speaker swapping is costly+hassle.
Your move, good luck, J
