Excellent post.
I agree about the different topologies; even so, I'll just add this. In the example quoted in my above post, the cct driven by the cLCLC psu is a mu stage which has very high PSRR so, in theory, the PSU should have little effect on the circuit. That my be so on paper, but my ears can clearly hear differences between rectifiers ... no, I can't explain it. Punch line: even with a topology giving high PSRR, PSU differences are clearly audible.

I agree absolutely about the top quality mains transformer!
I use Sowter (I'm in the UK) and I over spec it massively; expensive, but so well worth it in my limited experience.
Regards
Mike
