Power plant and power cords upgrades a real wow?

My opinion. Put your funds first into dedicated line and next upgrade your turntable cartridge. Power conditioner is down the line from those.

I agree with airegin. Dedicated lines! Piece of cake for an electician. You will hear the difference immediately. Then call Jerry, from Audio Magic. He will get your electric as clean and tasty as can be...When you start a garden you want to have fertile, rich, soil, yes? I feel the same way about electric in my rig. Many feel different about electric, but it has worked for this audiophool.

As your system is set for the most part, wondered what of the room. Have you given thought and resources to room treatments? This may yield bigger improvements that power cords and such.

Along that line however I would first invest in dedicated ac runs for my gear.

You have a sweet system. Post some pictures. Post your results as well.

I recently upgraded all my stock PCs with Shunyata Venom 3s-only $125 each. I also got a Blue Circle Thingee (its a power conditioner) for $300 with a 20 amp connect, and a Shunyata 20 amp Venon 3. I plug all sources into the Thingee, and my integrated amp straight into the wall (with a 20 amp cord).

I agree with Elizebeth that it will not transform the sound of your system, like a new source component will. But for my modest system, I think the benefit gained out weighs the cost of the upgrade.

I concur with the recommendations to have AC house wiring installed that is dedicated to the stereo system.

Concerning power cords, in addition to the brands that have been mentioned another maker of good quality sensibly priced cords, which I and many others here have been pleased with, is Signal Cable.

In comparison with stock cords, that kind of modest investment will get you quality shielding (minimizing coupling of electrical noise both from and to the connected components), heavier gauge/lower resistance, and perhaps improved contact integrity. Perhaps also some very minor degree of improvement in responsiveness to abrupt changes in demand for current, although that would have little or no applicability to your system since you are using an amplifier which is Class A, and therefore has minimal fluctuation in its current draw.

For a surge protector/outlet strip/line filter, consider this Brick Wall unit, which I and a number of others here have been pleased with.

I also second Brownsfan's caution against generalizing about this stuff. IMO investing significantly greater amounts of money than the cost of the modestly priced products that have been suggested is unlikely to yield commensurate (if any) benefits. While I generally don't question the perspicacity of those who claim to have realized significant additional benefits at higher price levels, differences in component designs, as well as variations in AC characteristics at different locations, IMO introduce way too many technical variables and unknowns to allow extrapolation of those findings to other systems.
