ProAc Response 1SC Amp

I have the 1sc. I drive them with three different tube amps. The main amp is a pair of sound valves (Dyanco design) mono blocks M60's, which I purchased over ten years ago for about $1K. They often appear on e-bay for about $500. Sound great. I also have and use the intergrates Cayin 100 and Cayin 80 tube units. They also work well. The 80 can often be had for $1.2K. Cayin has great sound and are a real value. I don't think you can go wrong with any of these amps since if you don't like the sound they are easy to sell off.

I would look at a Plinius. I have a sa-50 that I use interchangeably with my BATvk-75se. The plinius is not tubes but is very good and can be run class A or A/B..single ended or balanced. Maybe a little more than your budget but well worth an extra 2-3 hundred.

What about this?

Hello,
I like to say Conrad Johnson MV-55,or Primer 11 will good match your Proac Response 1SC.I use this set up to drive Proac response 2.5 sound pretty good.
CJ sound better than ARC class 60.

Audio Research Classic 60

Dodd Audio 8w amp

Music Reference RM10

Wavelength Junior

Dodd and Wavelength are pretty rare but the Audio Rezearch and Music Reference amps become available often

good luck and happy holidays

Sorry
11a more than $1200. A classic...holds its value well.

Conrad Johnson 11a.
very easy to bias. tube rolling is not a must.

heard the CJ years ago with the proac 2s. Great synergy
