I have dug up a review of the 8000A from 1987 by Malcolm Stewart.....and it isn't flattering.
He states that "word had it that the 8000A had been improved since its early days" and sums up by saying, "I could only conclude that this amp was among the most tonally thin and dynamically gutless of all the amps I've ever auditioned.
The vocalists seemed devoid of any expression in their voices, as no semblence of emotion or personality whatsoever emerged. To be honest, I found this amplifier boring and at times offensive: when it did manage to awake from its slumbers and make a stab at sounding dynamic, it was generally at the expense of some poor instrument in the upper registers, whose sound was catapulted at the listener with inordinate ferocity.
I think I'll stop at this juncture, as least said, soonest mended."
Now this is not necessarily my view, but a quote from HiFi Review during a mega test. They liked the Naim Nait, Inca Tech Claymore and NVA AP30; and quite liked Myst tma3, Onix OA21, Harman Karden PM655 and A&R Arcam Delta 90. They also didn't like the Mission Cyrus 11.
