I have been using Gryphon integrated for 3 years, never had any problem. I know that there is difference in software version from 1.1 to 1.4, the newer version runs cooler than earlier ones, probably to address reliability issue. The older version can be upgraded by downloading new software, I think.
In general, what I heard is that the Gryphon integrated amps are fairly reliable, which was my experience too. I did hear that its class A amps runs really hot, and may have reliability issue in not well ventilated set up. However, I had no personal experience with its class A amps at all.
