Some of these amps didn’t last in my system very long (the NAD and Kinki monos only 3-4 months, ie I just could not get some of the amps to sound right in my system) some were/are integrateds, and this list is in no particular order:
NAD M22 V2
Parasound JC5
Bryston 4B3 & 14B3
CODA CSiB & #8 V1 & S5.5
Kinki Studios EX-B7
Gryphon Diablo 300
Mcintosh MA9000
BAT VK-255SE
I still have the Gryphon and of course the S5.5, the Gryphon replaced the McIntosh in my main system, but honestly with some music I like the S5.5 more than the Gryphon, I have the S5.5 paired with a tube preamp and the synergy of the stack is really fantastic with the Mofi Sourcepoint 10s in my second system. As I mentioned too, the S5.5 has no problem driving B&W 804 D4s which are a really difficult load.
