Audio Research DSI 450 vrs. HD 220 against all tu

Acrylic....here is Marc Mickelson's (former editor of Soundstage.com and now founder/editor of The Audio Beat) response to a letter I sent him on the DS450: http://www.theaudiobeat.com/letters.htm

It sounds like he walked away with a favorable impression.

How do all the subsequent solid state/hybrid/class D models compare with the D100.2 ?

Cmalak, thanks for
the follow up and staying on tract. I am a big fan of Marc's and do not take his comments lightly. This is great news and maybe the solution for my wants/needs

Not sure what bad recording might have been playing while Jwm was in the ARC room, but on multiple visits listening to various recordings including my own live recordings that I had with me, the system sounded fantastic. It was antithesis of what Jwm described. The DS450 sounded less like a switching amp than any of ARC's previous models.

For the record, I used to be an ARC dealer but no longer work in the high-end audio industry.

I have not yet had the opportunity to hear the DS450, I love my AR equipment. Davemitchell, how will the 450 compair to my Classe CAM 200 mono blocks? any idea
