Innerstage vs R/C coupling.

I was asked about this three times in the last month by different about which is better and I tell them from my own experience it depends on the application.
My Fisher 50A and 55A amps are fantastic and make a lot of power for being triode connected,mainly because of the way they can go into AB2 without a hard clip.I'm thinking this could be due to the innerstage transformers because I also have a pair of Cary/AES SET amps with IT coupling and those are pretty dynamic as well.The IT trafos in those aren't the greatest but with better ones I think the amps would improve a lot as far as overall definition.
Now as far as detail and musical depth goes,R/C coupling holds an edge IMHO but IT coupling appear to have an edge in dynamics.Now,what I'm saying here is not cold hard fact,it is just from my experience from the amps that I have. I believe Mcintosh used an IT coupling transformer in one of their 1950s odd ball commercial amps.
