Thank for sharing.
I didn't expected this effect of spreading from distributor to the downstream. This is interesting and also a problem for me.
I have full silver and full copper powercord with different charecteristic, all will become rojak.
Bro wus,
I have gone through this power cord phase. My biggest problems were inconsistent sound characteristics across genres while playing, and not background not as quiet as it could be. Despite me using good power cords across components. In the end, I got rid of all power cords and used just one make. This got me the consistency that allowed me to tune the system and room and I got to the next level.
It is very important that your pre amp and power amp use the same brand of power cord for the sake of consistent sound and noise control. Source components can get away with rojak to tune the source incoming to the pre. Turntable power supply can use any cord that is quiet. Can use different models of the same brand, but keep to the brand for a consistent house sound.
My best power cord and the longest feeds the distributor as it influences even the rojak cords used to feed my sources. BTW I found that different lengths of the same power cord has differences. To my ears and system, a 2m length sound much better than 1.5m and 1m identical cords. I dared not try 3m length lest I cannot unplug once I test. The price per metre length is large.
