McIntosh MC501 or Audio Research DS450M for Magnepan 1.7

Thank you for sharing! Yes, the ARC DS450M is a class D amp and it has some mixed reviews but mainly positive.

 Read that it was paired with Magnepan at CES. Think this was the last D amp from ARC, probably due to slow sales.

But does not surprise me that you MC152 feels more powerful than a CJ with 250 class D since McIntosh underrates their true output in their specs.

I would appreciate Any other thoughts!

Thanks for the feedback. Just checked out the Sanders Magtech amp and looks like it was designed for electrostatic speakers with high current demand. Very interesting indeed! There are none for sell in Audiogon. Looking for something used that I could sell without loosing too much if I don’t like 

Thank you very much for the info. This is very helpful for my decision.

I was heading the MC501 direction but saw a pair of ARC DS450M at a good price. 

I will buy the McIntosh MC501.

Do you guys see a problem if I use an ARC LS27 preamp with a MacIntosh amp?

Thanks again!

Thank you so much fo your kind responses!
