Really good home electrical wiring.

I agree with the above posts, but recommend avoiding the Wattgate outlet in favor of the Hubbell. The Wattgate is a stock (hardware store variety) outlet, made by Leviton, and plated gold to look good. The Hubbell is actually manufactured from the start to be a superior electrical product, and sounds better, in addition to being manufactured with heavier and superior quality materials.

Good advice Albert.

Wattgate is a scam, plain and simple. My advice on the outlets is to get a few different samples from various manufacturers, test them for yourself. They should grab the blades of the plug tightly;they should accept #10 wire easily and use isolated ground type so all grounds are tied directly back to the main panel. Want to get tweaky?(I did) Use underground #10 romex installed inside SealTight or metal conduit all the way back to the main panel. The underground romex jacket is molded very tight onto the conductors to limit micro vibrations and by having it inside the metal conduit, it is shielded. Remember-don't use the conduit or SealTight for the ground return,use an isolated ground outlet with a ground wire run back to the main panel.I use Pass-Seymour outlets. A word of caution as far as ground rods. Some think that a separate ground rod is best, you know-have one just for the hi-fi and one for the rest of the house. If you do this and one ground is better than the other ground then what you have just done is to set up a voltage potential between the two...not a safe thing to do. You are much better off with a long rod driven into an area where you are certain the soil is moist.(away from the roof line overhang) There are also chemicals made specifically to be poured around the ground rod as it is being driven down in the ground to improve it's performance. Lastly-buy an Equi=Tech line balancer which is the best thing that could ever happen to your AC. They make models that would handle what you are planning but the model 2Q will handle 2000 watts and is made specifically for high resolution systems. If you want more capacity I suggest you buy a second. They are truely unbelievable-the best I have owned and I've had more line conditioning products over the years than any body I know. Good luck on your room.

I suggest you do not use house ground. Run a piece of 3/4" flat braid from each outlet to a 15' salted ground rod sunk into non sandy soil. If you can afford to do this, this is about as good as ground gets.

I have to jump in and remind you (as Deano did) that while a seperate ground rod may seem like a good idea, it is not safe due to ground potential between the two grounding points. In fact, it is against the National Electric Code to use a ground in this fashion. Driving an additional ground rod is ok as long as you ground the new rod to the existing main grounding point. Using a dedicated ground wire from the main grounding point (ground rod) to your dedicated hospital grade receptacles is the most effective and safe way to go. Be careful, a little hum won't kill you, but an unsafe electrical system will... Good luck & Happy Holidays
