excellent service and product

I've finished many audio kits in my time. I just recieved a 4P1L preamp kit and I have to say, I am very impressed. The packing was impeccable, every think was individually wrapped with great care. A quick glance at the parts included shows a lot of careful thought went into designing this kit.

I couldn't be happier, now it's up to me to do this kit justice.

Thank you Kevin!!!

Received the SU today and it works just fine with the Denon Zu 103. Very dynamic. Great looking small box and thanks for the additional by-pass switch.

Very easy order and prompt. Kevin freely offered advice and encouraged me to ask any questions. This is especially nice touch for beginning DIYers!

Thank you.

Kevin was very helpful with repeated inquiries with respect to using his products, the email thread with my correspondence with him is 28 emails long...Of course he is extremely knowledgeable but also courteous and professional in his diligence in getting back.

excellent support by Kevin, especially since I've always had trouble getting my head around transformer theory!
