Speakers for ARC REF.1 pre amp, VT200 amp

I have the ARC Ref.1 with a Plinius SA100MKIII amp and Dynaudio Contour 3.3 speakers. The Dynaudio's are a great full range speaker for this set-up. Also using NBS Monitor III speaker cables, Monitor IV XLR from preamp to amp and Nordost SPM XLR from Meridian 508.24 to the ARC Ref.1

The designers of the Bella Voce speaker by Shun Mook used a variety of amps to voice this extremely coherent 3 way. One combo they used included the VT200 and Ref1 with Nordost SPM, which in the room I heard them in was hard to fault. The BV speaker is seen in Absolute Sound ads and is one of Johnathan Valin's favorites for good reason. As others have said, YMMV depending on the room.

World Class Avalon Eidolon.

Stuart Taylor of ProAc uses Audio Research as his reference for speaker design. There is a real synergy with AR and ProAc, go listen to the Response 2.5s or 3.8s with AR electronics and see if you can do better, I think it will be hard.
