I got this nice email last week:
"Hello, I just want to say that i have purchased a set of m5001 from an audiogon member and I have some upgrades to the tube buffer. I am currently enjoying one of the best sounding hybrids that i have has in my system. In fact they performed so well with my current system, i decided to sell my Lamm M1.2 ref monos. The upgrades i made were replacing the sonicaps with euro oil caps, and roll the tubes over to CV4035/M8214 tubes. With these minor upgrades, these monos sing like no other amp I have ever own. Thank you for producing a class D hybrid that makes the reproduction of music the way it should be presented. Best Regards, Dave"
We have a dozen of these amps left and I'm going to drop the price 20% to an even $2k. This is a truly spectacular value. Enjoy!
