What is a good combination for Proac Res 2.5?

I've always run Proacs with tubes. Had a pair of quicksilver silver edn monos, but they were a mite dark. I'm running a pair of Response 2s with a pair of bridged solid state ARC D240 Mk IIs (pre is a tubed ARC LS-5 Mk III) and a pair of 3.8s with a pair of vertically bi-amped ARC VT-100 Mk IIIs (pre is a tubed ARC LS-16 Mk II). I like the LS5 better than the LS16, but the LS16 has a remote. I like the VT100s better than the D240s, but the D240s do have better low end control.

I believe that Proacs are, or used to be, "voiced" with ARC electronics.

I also own a pair and tubes do work very well. As does the Pass Labs Aleph series of amps. I have used the Aleph 2s and 3 with great results matched with a tube preamp.

Tubes...i had Proac 2.5's and they sounded beautiful. I used 40W class A Ming Da SET monoblocks and a Ming Da preamp...cost me $2200 including shipping from China.
