Onhwy61, I agree with you if you are using the term dynamics to mean "resolution". When I speak of a lack of dynamics with the Quads, what I'm referring to is a sense of compression, not its ability to differentiate between the gradiations between the softest and the loudest levels. With both my Quads and my dynamic speakers, in my room, with several different amps, when you compare the level of the softest sounds with the loudest sounds on music played at moderately loud levels, with the softest level being the same for both speakers, the dynamic speakers will always be slightly louder on the peaks. This is most apparent on loud large scale music. The Quad excels on lower volume levels where the dynamic speakers seem to have no life or ability to soundstage (I'm not speaking of my new Tylers however, which seems to be somewhat of an exception).
Sorry if I stepped on your toes re your SS integrated. I'm a tube-o-phile of long standing (never owned tube amps though until I got my Quads). The SS stuff I heard over my Quads, including some Threshold SA series amps with ARC tubes, although excellent, never made the Quads sing in the mid-range which is very important to me - as I indicated, thats why I got the Quads.....
Regarding your last sentence, since posting I found this same post on AA wherein the original poster has listed his system which includes an ARC Reference Pre-amp as well. He describes the sonic's as including warmth and lacking holography. He does not note a difficiency in dynamic's.
I would suggest to him that if he isn't getting holography its more likely a set up problem or an (unknown as yet) need for tube amplification, which would open up that mid range and high end, to go along with the rest of that great stuff that he has. FWIW it took me almost 6 months to fine tune my Quad/room/system setup.
I really doubt that he is a shill, even though this is his first post. I think he has a sonic problem with his system as set up and is looking for an easy solution. I just don't think these integrateds are his solution (with all due respect to your sensitivities).
