Dedicated outlet..suggestions..

The more dedicated lines the better. I now have three and am adding fourth shortly (I hope). One 30 amp circuit for each of my two amps, one 20 amp circuit for my front end, and hope to add another to separate the digital from analog.

The biggest difference was with the first dedicated line. You will notice the difference immediately.

If you can afford it I would recommend a 220V dedicated line going to a isolation transformer that can drop the voltage down to 110V with 2 balanced poles (rather than one live and one neutral). I did this in my last listening room and was very pleased with the results. Isolation transformers are not inexpensive. Hoever, it pretty much eliminates the need for additional power conditioners, and in my case there would have been 4 separate locations for power conditioners, so the isolation transformer was cost effective.

Pass And Seymour Spec Grade are as good if not better than Hubbell for less Money. Same outlet as the Hospital grade without the green dot. Saves you money.

One thing to be careful about if you use separate dedicated lines for the amps (and perhaps Rives' suggestion alleviates this problem) is the possiblity of a ground loop hum, even if the recepticles are grounded to the same box. I've had that problem with my separate dedicated lines for each channel of amplification, to the point that I float the grounds on my amps. I'm sure there are ways around this, but it is something to keep in mind.
