McCormack REV B upgrades. Better than a new amp?


I have read the testimonials about the stellar performance of upgraded versions of McCormack amp,especially the "REV B" level. A "used good condition" McCormack DNA-1 bought for 750.00, with REV B. upgrades added later is approx 1600.00 with round trip shipping costs. Would it make more sense to find a another amp that is newer, though USED between $1200-1500?? Also, do the McCormack upgrades hold up over time??

I have updated a number of DNA-1's and it's a much improved amp afterwards. The whole mother board gets replaced and it's a good idea to do it. The new board is simplified. The original had some circuit board issues over time. I'm also a big fan of keeping the amp that you originally owned and sending it back. You never know if someone abused the updated amp you purchased, or overheated it.
