Amp to drive Dynaudio C-1

I am currently driving my C1 signatures with an Octave V70SE. The only time it runs out of steam is when I run it with the EL34's. No problem with 6550's KT88's or KT90's. Dyn's sound best with high current amps. Unfortunately most manufacturers do not offer current ratings in their specs.

I absolutely enjoyed the C1's when I owned them awhile back. They surely need a lot of power as I recall to get the most out of them. I didn't use them with tubes, but with a Belles 350a Reference, which was a great combo. I'd recommend a x250.5, or x350.5 Pass amp. The .5's aren't as lean sounding, they are a bit more tube-like in presentation. I had a Pass x250 mated with Dynaudio 3.4's, and that was one of the best set-ups I've owned. Then dynamics of that combination was outstanding, my only nit was that is was a bit lean sounding which, again, I believe was addressed with the .5 models.

I am driving c1 with krell kav500i,if it was not best match with contour s1.4 with c1 is completly diffrent level,everything was improved from imaging to soundstaging,from bass to highs.I would say with s1.4 sound is Hi-fi with c1 high-end.

I'm second Pass Labs,start with 100w up all to 250w,the bigger the better

i drove c1s with an cambridge audio 840v2 and now with a bryston 3bsst. i thought both combinations sounded great.
