Dedicated power circuit


I am new to high-end audio and basically a skeptic. I never would have believed that cables and interconnects could make a significant difference in the sound of a system. After one year of experimenting, I have seen that the right cables can make a huge sonic difference.

My small system (Plinius 8150, Creek CD-43, B&W Matrix 803, Harmonic Tech Truthlinks and Pro-9s, Powersnake Black Mamba and JPS Digital PC). The system is connected to a 15 amp circuit that is not used by any other loads (although other outlets, etc. are on the circuit). I am using a Hubbell hospital-grade outlet.

I'm considering installing a dedicated 20 amp circuit.

My questions: Is this an important upgrade? If so, is there a special romex-type cable that I should use for the 60' run to my main panel?

Thanks for your advice.

Hi Joel; I put a dedicated AC system and ground in about a year ago, and yes it was a very worthwhile upgrade. I used 6 gauge stranded wire as it was already in place. The electricians connected the 6 gauge to a four 20 amp breaker submain, and then much smaller gauge wire to four Hubbell duplex outlets. For ground, I had 3 six foot copper rods driven into the ground within a few feet of the outlets.

One bad side effect of this dedicated system was a significant brightness in my system that was only cured by good quality power cords, ie I was hearing the "sound" of the stock power cords. Otherwise, music had a dramatically lowered noise floor, and became much more transparent. It cost me about $800. for parts and eletrician labor. Good Luck. Craig
