I also would have the TAD M600's at the top of the list. Check out sweetmusic69's posts over at AA. He went through a similar exercize on the CR1's and seems to be very experienced and meticulous in his search approach (he ended up buying the M600's).
There have been mentions that the M600's plus a somewhat more 'musical' preamp & source is the ultimate way to drive TAD ref speakers.
I was HUGELY impressed with all TAD system M600/C600/D600 however would agree that it may lean a touch too much to the analytical side and may not be as involving musically. Hard to tell though at shows, I always ask to play some 'normal' music, i.e. stuff I listen to and enjoy at home, but TAD demo's seem to always have only a limited musical selection of the cream of the crop high res master tape files and audiophile approved redbook.
Hi...everyone's taste is different. But I heard TAD all-reference system at Pioneer Plaza in Tokyo...and I brought my own music. What can I say...stunningly clear and no technical faults per se. I think the Glenn Gould Goldberg variations was exceptionally well delineated...and with all my recent tweaks, I have only recently managed to get where I think they are quite close. However, I found the density of the middle range of the keyboard a bit spare...not quite the power of the keyboard when you sit that close. Some might find that a bit cold...its was the 'meat' of the Goldberg variations where you feel/hear the body of the piano that I did not get in the TAD room at Pioneer Plaza. I cannot say if the recording is supposed to have it or not...I just know I get it at home and I prefer it that way...though I admit I got the body but had to fight to get the clarity, detail and it took lots of Ultra 5s and isolation to do it without losing that body. I suspect the body is somewhere in the electronics...cannot say for sure.
