Accuphase Class A or A/B speaker match Dynaudio C1

I had C1s on 200 watt McIntosh and the power guards went off. ymmv, but i think they need power.

I agree with everything said above especially the lower volume issues with these speakers. In a large room I just don't think a smallish amp is gonna cut it. Their impedance when measured was closer to 83 db. It's not a volume issue, anything will play them loud. .... It's a dynamic and subtlety issue that lower current amps cannot provide.

The Accuphase E450 which has 180w sounds less powerful than the E560 with 30watts Class A.
In a small to medium room, the Class A Accuphase should be able to drive those C1s.
I heard the E550s drive those ATC SCM19s which are more power hungry than the C1s. Drove them to high levels but at extremely hi levels, the E550s could use some more power. But we are talking about real loud loud stuff.
Good luck.

Indeed a strong case has been made for both the Class A and A/B. My impetus for going from the Revel Studio’s to C1’s was down size. I was driving the Revel’s with 350mcx mono’s. That being said, I can attest to the C1’s love affair with power. One would be hard pressed to win the curtain test when comparing these beauties along-side any floor standing 3 way up to 20K. They impressed me. Perhaps, as I read in a post “E-450 E-550”, the best solution is to Demo the set up. My other consideration which I have now placed into the mix is, the E-550 may? Limit the range/scope of future speakers. Just another thought. Thanks for everyones input. Still struggling.

I am driving the C1's with a Jeff Rowland Concentra II, 150w into 8 ohms 250w into 4 ohms. This works fine but is probably the minimum I would find acceptable. I have also heard the C1's driven by Simaudio W7, this was not lacking for power either.
I have found the sound balance to be excellent at low levels with my set up, none of the hissy/tinkly sound you get with metal tweeters
