Installing Dedicated Lines.... Need advise

Several years ago I did a lot of wire (10/2) and outlet comparison testing’s (check out my older reviews and comments).
I concluded the following to answer your questions:
1) It's a personal matter of diminishing marginal returns.
2) I did not notice a difference in sound when my outlets were located close to each other or separated by six or eight feet or so, however there is nothing wrong with the idea of separation of outlets.
3) I did notice a difference in sound dynamic’s when using different high-end outlets and it's okay to mix and match different outlets and AC wire to create the desired sound you want to achieve.
Feel free to email me if you have specific questions.

In theory, separation of any cable is better than no separation, but whether or not it makes a big difference???

I have noticed a big difference in outlets. I started with Hubble hospital grade, then PS Audio Power Ports, which made a noticeable difference for my amp, but not as much for my source components. Recently I have installed a Watt Gate Gold (amp) and a Silver (sources) with definitely better sound than the Hubble, or PS Audio. Probably depends a lot on your particular system and incoming power as to how much improvement you would gain, but I am now a believer in outlet and power cords. They do make a difference.

Contact VH audio and they can direct you. Their familiarity with numerous systems would be valuable. Also consider their panel mount AC filter and surge suppression. I just heard one installed at a friends. The improvement was not subtle. Jallen

Make sure you hire a qualified electrician who is also trained in stereo home installations. We can thank the popularity of home theater custom installation for electrical installation designed to reduce ground loops, hums, isolation etc.

My electrician suggested a separate pony panel from my main system. He also put in a large surge suppression to protect my equipment that would not impact sound quality. He also recommended separate lines for analogue and digital. All lines were designed for 20amp service.

Any electrician can wire a system for audio, but it takes good electrician to wire a system for both power and performance.
