Suggestions to replace amp for Proac 1SCs

I have successfully driven the 1sc's with a Pass Aleph 3 basic. The Pass is 30 watts per channel, class A architecture. I never ran out of power, and the Pass had a very smooth presentation, especially in the midrange. It is the most tube-like solid state amp I have heard, perhaps due to its class A design. It fits well with the 1sc's philosophically: very high build quality, top ranked sound (Stereophile Class A when it was still in production), least costly of a respected manufacturer's line, and small size. I know the Aleph 3 is out of production, but I have seen used units for sale from time to time on Audiogon and other auction sites. The design and build quality are virtually indestructable, so a used unit should last for many years and offers the virtue of having already been broken in. I don't have a recommendation for your preamp, but I would think a tube unit like the Audible Illusions 3a would work well. I agree with sc53 about the benefits of using a good sub with the 1sc's.

YBA Integre DT...if your not looking for separates

I own the 1sc's and in my room 12x15x9h they sound great with Sun Audio 300B, 47lab Gain card, VTL tiny triode and.
