Amen to that brother. I still insist that dedicated power was my best tweak to date.
What's 10 Volts between friends?
Moving into a new house 3 1/2 years ago really re-kindled my interest in music and audio because it was a move that put me about 5 minutes from work and greatly reduced my out-of-town travel time, meaning that I had a lot more opportunity to listen. It also meant going from "perfect" power to both a power grid that isn't as good and a house that is wired like crap. Watching the volt readings on my surge protector, it dips as I turn more gear on, quite regulary running below 110 volts. Way too much stuff on one circuit.
Yesterday, I finally had the wiring reworked and some dedicated circuits brought down (of course, this is all at the complete opposite end of the house from the breaker box, so it wasn't just a couple hundred bucks). Now, turning on the gear only barely fazes the volt reading (it still does somewhat), and CRIMINY! what a difference! To say that everything is crisper, cleaner, etc. only begins to describe the improvement.
If you have problems with your power and have not yet run dedicated power lines to your system, do so as your next upgrade - you won't regret it. -Kirk
