I’ve got a pair of 2Ci I use in a second system with a Antique Sound Lab EL-34 based integrated and it’s not a great match. The 2Ci are a bit on the warm side so a vintage sounding tube amp is not a great match unless you like a very warm sound (I don’t). I don’t use this system much so no great need to upgrade, but if I did I might try some solid state amps. Having said that, the V70 would be a good match. I had a Classic 60 (essentially the same circuit as the V70) and it was a good match, but I didn’t want to have to worry about the cost to replace all the tubes so I sold it. I’ve never heard an Atmasphere amp but I’ve heard lots of good things about them too.
Vandersteen 2ci with tube amps
What are your thoughts on tube pre and amp with the Vandersteen 2ci? I can acquire a Audio Research LS2 with a V70 from someone that is near me.
