Default Power supply rails for NAC 282 & 252 ?

I think that I understand the Naim hierarchy for Naim Pre's and PSUs, but reading the specs for the PSUs doesn't tell you what supply rails are actually utilised by the 282 and the 252 in each pre/PSU combination.

Can anyone point to work or investigations carried out which identify the supply rail requirements of the Nac 282 and the 252?

I'd just like to understand what is actually going on.

Many thanks

I don't agree with all the conclusions reached here, but there's still a ton of good info:

Thank you Jeff, I have previously read the acoustica site with interest, I will re visit, perhaps i missed something. I didn't find it terribly easy to understand.
