can anyone explain to me the advatages of the two rectifiers and two torros per PSU?
Are there definitely sound enhancements, when using those?
Because then i need 4 torros with 9V, 0V, 9V. and who has them in stock?-where to buy them?
ist it possible to reduce the 18V,0V, 18V of my torro to 2x9V?
regards,
Ralf

supposedly that improves channel separation.
But nobody has been able to provide any concrete proof of it so far.
I ran 36v rails without any problem, so far.

IMHO - - If in a specific instance doubling the trandformer and rectifier really made a significant (as in audible and measurable) difference in channel separation, onemight well ask what was wrong with the amplifier design and construction that it was so suseptible.
Looking at it another way --Considering the cost of a second transformer and the space to hold it might that cost be put to better use improving the amp circutry?

Reply to myself --
Don't forget the situation with very high power amps - finding a toroid with sufficient VAC for two channels may be difficult. In such situations two toroids may be the simplest solution.

Two rectifiers per PSU might be necesary to achieve a regulated positive and negative rail voltage.
I think there is one point : most of the time the following isn't checked:sam9 said:
is the total VA unchanged? are you comparing having 2 100VA toriods vs 1 200VA or are you comparing 2 200VA vs 1 200VA.
It makes imho sense to use two toriods. Low voltages (less than mains anyway) require large currents to get a certain amount of power.
Using one toriod a music peak in one channel will lower railvoltage for both channels and thus influence the sound.
Using two toriod's eliminates this problem.
