How does my MF A308 compare to modern integrated amps in the $3000-$6000 range?

I also have a MF 308 integrated and have always been happy with it. Some years after it was discontinued, I had a conversation with MF manufacturer's rep for the US and he told me that many considered the 308 integrated one of the best sounding amps MF had produced to that date. Also, he used one for his personal system and had compared it with other amps, but had no desire to replace it. As long as it is working properly, it's a keeper.
