Aye (raises hand) with VR-11s of my bro and more recently at a show.
Yes they are very,very good. My brother likes 'em in pedal to the metal mode while I love them more in Triode mode. They can drive anything I can think of in either. Now THAT is special right there. Having two amps for the price of one that is. I was with Luke a few days ago and told him so. The S2s were showing with Utopia EMs. Too bad Jim was down and out last weekend. He would have enjoyed the show.
