Audio Research DSI 450 vrs. HD 220 against all tu

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

I have not had much experience with the CAM200's but have listened quite a bit to the CAM350 mono amps, so if they are similar....

The ARC sound is brighter (in a good way) like the performers on the stage are illuminated by brighter stage lights. The CAM350's are really nice sounding amps, but they are darker and softer sounding than the ARC gear. The ARC sound is a little more dynamic.

thanks davemitchell. My Classe monoblocks sound very much like the 350,s. You are correct about them sounding a little dark as they were perfect for my Thiels. Kind of looks like the 450 will go well with my system.
