The best solution would be to call Hank Wolcott himself. He is friendly and knowledgeable and based on the numerous conversations I have had with him, he seems to remember the details of all his projects.
What most people do not know, The Bureau of Standards in Washington D.C. uses his test equipment as the standard for measurements. That certainly says something about his design ability.
I've sold 7 pair of Wolcott mono blocks in the last twelve or fourteen months. One pair of Presence went to the Dallas Symphony Conductor. He owned a very high end transistor amp, and after ten minutes in front of my system, made me call Hank at home and order that evening (shipped overnight Fed Ex).
Short answer is call Hank. Send them back to him if he says you should.
In the end, if the performance can be made even close to the new Wolcott Presence mono blocks, it is worth the time and money to do so.
