My JBL 4425 pair sounds pretty good. Except the problem above.
My setup is:
Amp: Audio Research CA50 valve
CDP: Marantz CD 16 w Benchmarkmedia DAC1
Inter cable: VDH The First Ultimate
Spk cable: VDH CS 122
Is that the nature of JBL monitor speakers?
I listen to vocal a lot. How to make them sounds lucid and sweet? (I mean by changing amplifier or source.)
