That seems to mesh with other opinions I've come across regarding super systems. In fact Michael at cornflake mentioned a customer who used six brystons 7B monoblocks with a pair of vast PMC's. Apparently it didn't sound as cohesive or natural as using a single 4B running in passive mode! A rather unfortunate result, given the money and space consumed.
I had a quick look for those larks you mentioned. It seems the site has died:
