Petar, you know my set-up well, and your remarks are correct within the context of that knowledge. However, despite the obvious technical problems, Etta's voice - per se - is actually - remarkably - accurate, with plenty of body and soul. While I still aim to address the issues you've raised here, I think what I'm hearing "overblown" in this case are very sudden, sharp bursts of air pressure that over-stimulate the microphone diaphragm, and then the reverb boosts the already-overblown ULF, followed by a DAC that passes DC, followed by amps that are willing and very able to boost those signals with the same sharp rise times as the original events!
Right now, in broad terms, I'm thinking like Decoud. Somehow, there is too much ULF getting to the amps via the CD chain. Again, it has not happened with LPs, despite the potential there for rumble, and other ULF problems. IF I get more, deeper (U)LF from CDs, I never noticed it with the ML2s.
Perhaps I have unwittingly biased my speaker LF to compensate for previous speaker/amp issues, and I will certainly follow up on this possibility. However, the more I think about it, I think something is going on with the iDAT's right channel. I'm thinking perhaps the ML2s simply crapped out on this "inappropriate" ULF, while the MA-9S2s just amp it up, and they make the drivers do what they want them to do.
Best regards,
