amp for vandersteens

Even an ancient Mc 250 throws a big 6’ tall Diana Krall image with a properly setup set of II. Really just about any well designed neutral amp with decent damping factor ( to control the acoustic coupler) will do well. The mentioned PSE while rare has some history and merit w Vandersteen- Dick the engineer behind PSE is co designer on the new Vandersteen hi pass power amps.
Hafler, Bryston, B and K, Amber, Apt, Sumo, GAS, etc recapp and go !!
the Belles is wonderful as mentioned
for tubes Rogue and Quicksilver or a Music Reference RM-9 or -10
have fun, enjoy the music

I've used YBA preamp and amp with Vandersteen 2 ce for many years. The combination is very synergistic and provide the closest tube experience without the tubes.

I've owned Vandersteens for 25 years plus and nothing comes close to tubes........I've heard them with Quicksilver, Audio research and Rogue with magical results.......I've also powered them with solid states from Bryston,Jeff Rowland, Rotel, NAD and more with good but not magical results........stick with quality tube amps and you will be very happy...... 

My 2Ce Sig IIs sing with the angels when driven by a Vincent 331-SP hybrid (SS/tubes) amp and a Schiit Freya (SS/tubes) pre.
But, this setup is in a dedicated room acoustic treatment.
The room will affect half of what you will hear.

That speaker is pretty tube friendly. We've had a number of customers with them over the years. Tubes really make them sing. In most rooms 100 watts or so is nice.
