Power direct from the wall, or Power Conditioner?

[f1eng]

there are 2 types of power conditioners. One is only trying to clean the AC, the other tries to improve the current delivery capabilities.
e.g. the Audioquest Niagaras can deliver up to 80A for a few ms, the big Accuphase can do the same. PS-Audio can also deliver much more current that the wall plug (only 10/20A).
Also these devices can provide the power much faster. Epecially a switching PS can benefit from this additional power. Transients are reproduced much better .
And yes, theoretically a very good linear PS should not benefit from a power conditioner, but still a lot of them actually do.
Also a power conditioner without very good power cords can we a waste of money.

Here in the Uk we have 240 volts and 13 amp fuses.
That means there is 3120 watts of power available. Why anybody would imagine that that is insufficient for any part of the hifi, even without any reservoir capacitance, is a mystery to me.
I suppose good marketing to people who aren't technically minded combined with the placebo effect/ expectation bias may do it
