And yes, i have always wondered what a really nice core could do for a power tranny.

cores meant for opt's can be used for power traffos and vice versa......it is just about size, winding geometry and power handling.......IOW judicious use of materials is key......i know of no law that says it can not be done....

Didn't say that, just that the purported benefits were rather dubious. A properly designed silicon steel transformer with lower internal resistance and leakage inductance looks to be better than a supermalloy monster over twice the size/number of turns. The money is better spent for shielding, good filter capacitors, RFI abeyance, and other measures to make the supply voltage as clean and pristine as possible. You'd have a lot of money left over, too... That's all for now.

How to measure degree of niceness?

I agree about low DCR, but I would prefer higher leakage inductance, but lower capacitance between primary and secondaries.

like i said if its generic psu where transients doesnt matter. Just a statement is amplifier is just the modulator for the PSU so no matter how good is the modulator if the source of power is not fast and quick with massive transients things are different...

Lets consider if we have distortion figures are like still .2% but still it doesnt matter as long as the core of the transformer makes the sonic difference...

in terms of mathematics we are already there but we dont get that sonic beauty without proper materials. People like Audio note have made the observations and conclusions and I hardly see any people complaining about their products...

I found one guy who does amplifiers and he always says that things are ot perceivable when it comes to the last 5% but when I auditioned his speakers were very bad I dont understand how come people conclude without proper high resolution speakers.

I am following Audio notes perceptions... nothing wrong in them I have personally auditioned their products with sonus faber higherend 2 way speakers and they sound fabulous and extremely good and natural... no second thought... so guys I dont know how many have achieved it without good materials in their equipment.

you lost me on the higher leakage inductance....
