Class D and Power Cables

Ralph, I don't necessarily disagree, and I would suspect that in general Class D amps may indeed tend to be more sensitive to power cord differences than other classes. But wouldn't the limiting of high frequency high current bursts typically be mainly a function of the house wiring, not the power cord, due to their difference in length, and hence inductance?

Although it would certainly seem conceivable that in some cases other power cord effects, such as voltage losses and coupling of amplifier-generated noise from the power wiring to other parts of the system, could be disproportionately affected by the power cord in comparison to the house wiring.

Interesting point, Ralph, which I recall you having mentioned in another thread some time ago.

Conversely, would it follow that if the AC line voltage happens to be GREATER at the location of a particular listener than the line voltage that the amplifier design is optimized for, that (everything else being equal) a relatively narrow gauge power cord that drops significant voltage might provide better results than a very heavy gauge cord?

On the other hand, though, especially in the case of a Class D amp that has very large fluctuations in its current draw as a function of the dynamics of the music, I would imagine that any such benefit might be outweighed by the effects of voltage FLUCTUATIONS resulting from the combination of fluctuating current draw and significant cord resistance.

Audiolab, thanks for your comment. :-)
