Speakers for Audio Research VT100MK2

Vandersteen Quattros are nice with AR amps too. The Wood Quatrros are even nicer.
Green Mountain Audio speakers work well with ARCs too. That's what I use with my VSi60. My friend uses Thiels (3.7s?) with his ARC (VS60), and it's very similar to my setup. I think any of the so-called "time-aligned" speakers are good matches with ARC amps, although I don't know why this would be.

Proac is a great match with ARC.

I agree with Vandersteens. Dunlavys sound better with a sweeter sounding amp.

Vandersteen is a natural with ARC. A pair of 2Ce Sig. II or 3 sig. would be excellent.

A few years back, a friend of mine paired them with Dunlavy IV's. They sounded great.
