Attn: McCormack DNA 0.5 owners

I purchased a DNA 0.5 used about 5-6 months ago and love it, I do have a question about it though. When I turn the amp on and off, I get the dreaded THUMP, is this common to all McCormack DNA amps? The amp I had prior to the McCormack had a little thump, is this a problem with most ss amps? Will it go away if I send the amp to SMC for upgrades? I have been thinking about sending the amp to get a Rev. A upgrade done. Any help or info would be great. Thank you.

Do you hear the thump the same when shutting down the components in different order? Do you shut off the preamp or source before powering down the amp?

If a Revision would solve the problem, what a bonus! You'll really appreciate what the modded amp does for your system.
