Straw man, dude. If I give you a line cord with 25 ohms of series resistance to use for your power amp, you'll have an audible difference. ""
We agree on that. However, if you would re-read his post, you will see he said preamp.And, no supply voltage measurements were stated yet the assertion was that the supply voltages were affected.
How does a supply voltage drop cause more bass in a preamp.
How much inductance is required to screw up a supply that has very little load?
How much inductance do you imagine a rod of hi mu material placed an inch or so from the line cord to have? At 60 hz with odd harmonics, are we now saying that there is sufficient inductance to starve a well designed power supply?
mkj: ""
The question isn't, "can one hear a difference between a wire which is suitable for the purpose versus one which is clearly unsuitable?" but rather, "can one hear a difference between a normally competent line cord (Home Depot, for example ;-) ) and those with fantastic claims and prices attached to them?" ""That is not my question, though it is a valid one.
My question is, a line cord with no obvious restrictions in it's ability to carry current, altered the sound sufficiently for Dan B to state such.
I do not deal in strawmen.
As stated, the thing didn't do much at frequencies first looked at, but yet does so at 100 hz.
That says inductance to me.
Check the supply voltage. If it isn't drooping enough, the explanation is no longer plausibe and must be discarded as unsupported...or verified. Simple.
Then look at the loop..
