I have had the amp for about 6 months now. I have used it with Silverline Sonatas, and now am using it with a pair of Bottlehead Straight Eights. I have found it to be a wonderful performer with both speakers, and has never run out of steam on either. The midrange is wonderful as well as the bass. I particularly like the compact size and styling as it fits into my rack perfectly. I too have dealt with Kevin Hayes, and he was very obliging and pleasant to deal with. Happy listining.
