Importance of Power cords feeding Conditioners


I have heard it said that the most important power cord is the one into the distributor block. Well specifically I have heard it said at the Nordost roadshow demos, by the ever young and enthusiastic Lars.

At the recent UK show, he compared an all Red dawn cabled system, with an all Valhalla system. He changed one cable in the red dawn system, an Odin cable into the QB8 block on the red dawn system and sure enough, it sounded better than the all Valhalla system.

My question, if this is true and it seems so to my ears at the demo, that it is, is it equally true for all power conditioners? In particular, I am using a Pure Power APS 1050 regenerator. This is supposed to isolate the system from the mains by regenerating an AC wave form from a battery supply. In theory, this should make it immune to power cords feeding it. I will try some experiments myself, but has anyone got any comments about this? Thanks

it seems that it is just as important for AC regenerators as well. The reason is that AC regenerators regenerate the output AC sine wave using electronics (called a power inverter) that runs off DC power that was created using the AC from the mains/wall outlet. Without bogging you down in too many details, inside the AC regenerator there is a sine-wave generator that runs off DC (created from the AC from the wall outlet) & this sine wave is fed into a power amplifier that amplifies the voltage to 120VAC & also provides the capability to supply several Amperes of current (that your CDP, DAC, TT, preamp, power amp, etc, etc can use). This power amp is also running off DC (created from the AC from the wall outlet). So, if you end up using an el-cheapo AC power cord & you have distorted AC going into your AC regenerator, then, the electronics inside will run off a corrupted DC power supply which will show up as less than the best sonics possible. So, use a better/best power cord within your budget.
