I owe it to Craig to let everyone know the great service I have received from him. It started in early January when I began inquiring about purchasing one of his amps. He patiently answered my many questions and wasn't upset when I ended up buying a used HD300 instead of a new one. When I began having some issues with hum he helped me troubleshoot a grounding problem in my own DIY DAC. When this didn't completely eliminate the hum he had me send my amp into him. He fixed it the day after he received it, and went beyond the hum issue to add new upgrades to improve the sound further. Specifically he added a circuit to compensate for the rising impedance of HD650 in the high frequencies. He only charged me the parts cost for this upgrade. He also mentioned in an e-mail that he is willing to share a schematic of this upgrade so that other HD300 owners can benefit too. He shipped my amp the next day and I received it early this week. The amp sounds excellent, with a blacker background than before and zero noise even with the worst 6AS7 offenders I have. I am a satisfied customer.
BTW, my favorite tube combination so far has been Brimar 6SN7 with Tungsol 6AS7.
