Amp to drive Dynaudio C-1


I'm currently running an ARC VT-100mkIII but it runs out of juice when you are pushing it. I have been told that pass amps sound great and they give a tubelike quality. I would like to stay with tubes but for the power I need it is going to be too pricey. Your suggestions are welcome.

I have heard the C-1's at my local Dynaudio dealer many times with a plethora of different amps, no combination sounding better than the current one of C-1's and Audia Flight integrated amplifier. Not sure if it's the model one or two. Fanatastically killer combo with the newest Shunyata signal cables and power products. I was blown away. I have always liked the C-1's a lot, but I have never heard them sound better.
C-1's are great, and I have heard them sound tremendously impressive with Gamut mono blocks. If I had C-1's, that's where I would go.
I ran Dynaudio Contour S1.4 with McCormack amps and it was very good. Fast, clean, nuetral and musical. The dealer carried McCormack and CJ in addition to Sim Audio. I have heard all three thru the Dyns and all are more than capable.
I ran mine with a Musical Fidelity Tri Vista 300. A nice warm sound with buckets of power in reserve. Tasty!
I second Musical Fidelity. In addition to the Tri Vista 300, a solid state model to consider might be the M6PRX, a 260w/ch dual mono power amp. The M6PRX has received stellar reviews, but for whatever reason, you don’t hear much about it here on Audiogon.

I use it in combination with the solid state M6PRE to run B&W 804 Diamonds in a room that doesn't remotely lend itself to warmth (hardwood floors, plaster walls and ceiling, and only a few pieces of upholstered furniture) yet the sound is still remarkably warm.

There’s a used M6PRX available on Audiogon right now, the first one I’ve seen listed in the past 6 months or more. The seller (who I don’t know) is asking $2100, which is a very good buy. List price new is $3500, and even at $3500 the M6PRX compares favorably with amps that cost more.

The seller’s ad says he has been using the M6PRX with Dynaudio Contour S3.4s with excellent results.
