Dear Mijo, You don’t need to teach me about the electronics, and no, I did not own the Parasound amplifiers any longer by the time I upgraded my 845PXs. In fact, my experience with the Parasound JC1s was entirely driving my M1s, which were completely stock in terms of the backplate components. With all respect to you and your quest for Nirvana, I perceive that the difference between you and several of us is that you want a perfectly flat in room response, regardless of the necessary interposition of the electronics (digital or other) necessary to achieve that. Whereas, I prefer the purest pathway with the least possible processing of the signal, come what may, with the exception that I do treat room reflections in my listening room with various wall panels and tube traps, etc, but that sort of thing is after the fact. You are operating on the signal in the digital domain before the fact. That (digitally correcting for droops and peaks in your listening room) has to be why you are stressing the MA2s, because there is no way they should be stressed purely by driving the Sound Lab speakers in the manner that you espouse. I tried equalization by signal processing once and hated it, but I admit the methods have come a long way since then. So I am curious to hear your system. Perhaps next time we go to northern Vermont I can stop by.
As to your response regarding how you measure in room response, "using a very expensive Earthworks microphone", etc, that is not a complete answer. Where do you place the microphone? At what SPL do you map the response deviations from flat?
