I certainly do not doubt that many have had excellent dealings with Kevin Deal at Upscale Audio. Considering the source willing to put their reputation on the line for the man says something about him as well. However, I can only go on my own experience with him, which was not positive. I'll accept the fact that I am probably an exception and not the rule. Andy at VTS and Brendan at Tubeworld both sold me a pair of tubes which were microphonic and they both offered me a prompt no questions asked refund. Kevin on the other hand offered me excuses. That is what I am basing my opinion on. Nothing more and nothing less.
