Albertporter is busy at the HE Show this weekend, but I'm sure that he would tell you that the Wolcott Presence 220 monoblocks are the best amps that he has come across in about 15 years of Soundlab ownership. He uses the Soundlab U-1, and the Wolcotts, with Aesthetix Callisto Signature Linestage, and Aesthetix IO Signature Dual Power Supply Phono Stage.
I know Albert very well, and I know that he has tried many things over many years, and considers his current setup to be the best he can find, cost no object.
Given this fact, I think that the Wolcotts have to be considered in this role with the Soundlab speakers.
