Dedicated power lines for audio?

I recently added a dedicated line along with isolated grounding. A very positive improvement in the sound quality of my system. Highly recommended. I used quite a bit of the information from several of the Audiogon threads. Thanks. The one thing I didn’t gain any improvement on was the directionality of the main wiring (as Redkiwi says). I wasn’t able to here an audible difference by changing the direction of the wire. I followed the same process and ran the wiring on the outside of the house. I actually tested is four different ways (switching both the hot and neutral wires). I’m curious if others are finding that directionality makes a difference? I used stranded 8awg from the main breaker and a combination of 8awg and 4awg for the isolated grounding (yes it is probably overkill but what the hell). The main wire was pretty stiff and somewhat hard to work with and barely fit into the wattagate screw down terminals. The ground wire was Esoteric Audio car power wire. It consists of many strands of copper and is very flexible. I fed the main line in series to two wattagate receptacles (about 6' apart). From the wattagates I used short runs of 8awg to a copper grounding block and then approximately 10’ of the 4awg to the outside grounding rods. I used two 8 footers about 18” apart. The best comment that I get is when my wife asks me if she can water my rod when she’s done with the garden.

i'd like to thank everyone for all of the helpful info. i just finished installing 4 new outlets on 4 circuits from a sub panel run off of the main box. i went from a 40amp breaker, ran 3 conductor 8 gauge to the subpanel, drove a separate 5/8" grounding rod from the subpanel, used separate neutral and ground wires for each circuit and used hubbell hospital grade outlets from hcm audio(24.75ea). wow!!! what a difference. increased detail AND smooth involving presentation not to mention a bigger and better image! i couldn't hardly listen to my system during the daytime before.....too hard sounding. i have been listening all day while two window ac units and a dehumidifier and my computer are all on and it sounds terrific! the only thing i can add to the discussion is i am going to try a quieting transformer. my local spectral dealer has one hooked up with his 2c3d system. i will report back when i get it hooked up. i am hearing info for the first time on many cd's!

Hi Tk; and congratulations on your dedicated AC system. It sounds almost exactly like what I had done this spring. And I agree with all your comments about improved music quality/character. HAPPY LISTENING. Craig.
