I have tried/owned so many power cables through many years, including many DIY versions.
It all started after trying a Synergistic Research Master Coupler that a dealer provided. I was convinced as some of you have stated that NO WAY can just a power cable improve the sound.
But it did.
If your system and ears are up to it, you can clearly hear the differences in cables, be it cable inductance, shielding, configuration, conductor type, design etc.etc...
Today, I own all AQ Dragon power cables. I also own the AQ 7000 power conditioner. There is a strong synergy with them and the Power Conditioner. (IMHO, they were probably designed together)
