A likely explanation , beside the one that the ps disturb other equipment . So called linear supplies also disturbs the feeding net by a great deal their input current is very distorted . If had the brains to design a supply I would design a supply that draw sinusoidal current from the net with a power-factor close to 1 this can be done with switch-mode and LCL filters (I work with such devices but they are in the MW range ) Lore ? I think everything never than the direct heated triode is considered bad ;) . It is quite possible to design both bad and good supplies with any method, as folklore is part of audiophiledom it is hard to sell in a good switch-mode supply, instead you put together a run of the mill linear supply in nice looking aluminum case and you earn money :) -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
