I think what Ken was pointing out was that (a) the AIC-10 is starting to fall off it's pedestal a bit, where people are finding more faults with it, and giving feedback like preferring it off the speaker taps. Which means you may be over paying for the performance, even from a subjective perspective. And (b), reverb if you do want it, you can find it cheaper used. There's one is our FS forum right now, so maybe you could jump at it and net one for substantially less money, this better positioning it's value due to (a).
Not that I'm a fanboy, but I've seen enough of Ken's kit across the threads to know that he also drops stacks on components he finds subjective value in. So that even sets a better context for his insights above.
+1 about nabbing that 1/2 price AIC-10 in the Amplifier FS forum.
But from my guess, I just kinda fell a different amp would work better with the TCs...
