Hello Dan2112, and others. The Wolcotts are extremely good, I have owned two pair of VERY expensive mono block amps just before this pair arrived. By comparison, these are a bargain! Unfortunately, for the final word on ultimate performance, I need more time. The actual break in on this pair is only about 20 hours along. A trip to Belize (Central America) really set back my schedule. However, I hope that in the next week or two, I will be able to tell much more about them, as I accumulate more hours. I also plan to install some premium grade tubes (I already have them ready) and report on the effect of those in the circuit as well. For additional reference, I still own the pair of class "A" SET's that have been my standard for the last (nearly) two years. Some encouraging news too, Wolcott is now completely up to date on his production schedule, and is reported to have quite a lot of amps ready to ship. I think there are only a few that are pre-sold, so members interested in this amplifier will not experience the delay I had. Unfortunately, I placed my order just when everyone (including audio reviewers) were all making the same request. That, in addition to the CES, was a bit overwhelming.
