    Regarding power supply, would it be better to have PSU in a separate box away from the valves.. Is this more beneficial than dual mono design or mono blocks?

    yes I tried to find your post with no success
    ou might slip, you might slide, you might
    Stumble and fall by the road side
    But don't you ever let nobody drag your spirit down
    Remember you're walking up to heaven

    Don't let nobody turn you around
    … Walk with the rich, walk with the poor
    Learn from everyone, that's what life is for
    And don't you let nobody drag your spirit down

    PSRR may need some explanation, unless I'm underestimating the electronics knowledge of typical forumites.

    Hmm yeah I considered explaining it... but didn't Hey if yer going to get accused of being patronising at times you have do the opposite now and then to keep em guessing I'm off out in a mo with a few beers to watch Jools Holland at mates place so if you would care to do the honours Andrew?

    PSRR stands for power supply rejection ratio. Without getting too technical it's basically a measure of how well an amplifier shrugs off the inadequacies of a less-than-perfect power supply.

    BTW, going off at a slight tangent, I think it would be helpful for people not to get too hung-up on the "power" side of a power supply and instead think of it as a voltage supply. Sure, for power amps it's important to have some power available, but mostly it's a steady voltage which is required. Actually, that's still true for power amps - but the voltage needs to hold steady under more demanding conditions.
    Anyway, the idea that a "good power supply" means one which will supply more power - and is therefore big - is over-simplistic in my opinion.

    Good post. Explains a bit. So it's very important to have a very high PSRR and equally important to have a very "rigid" regulated power supply, so ?steady regulated voltage holds under demanding conditions??????

    Not necessarily.. 'Best of Breed' Amp topologies often don't benefit from a regulated supply.
    Lesser circuits typically need all the boost they can get... from any quarter.

    Only news here IMO is the lengths we as Audio Weenies will go to in our search for the ultimate hardware advantage..
    To Replay our cheap mass-market recordings of dubious quality...
