Cleaner AC Source for Better Sound

As I read these responses and those in other threads, my best bet might be to upgrade the AC cord for my amp and plug it straight into the wall via an upgraded duplex outlet on a line separate from the components. Then run the TT, tuner, CD and preamp to something like a Chang LS 6400ISO or a PS300. Seems like this would provide a good and clean power supply to the front end stuff and provide solid power to the amp, albeit without surge protection. I live in an area of California where lightning is nearly nonexistent but I do have some concern with regard to power spikes. Perhaps the thing to do is go the "direct-to-the-wall" route for now and consider a more amp-ready unit later. Reasonable? Also, would it be overkill to use something like the Noisehound in the second outlet of the duplex where I plug in my amp power cord? I would like to limit spending to about $880 and it doesn't seem possible to do ALL I want at this price. Isn't that ALWAYS the way, though?

I have no connection to Blue Circle. They just seem to make electronic products that "sound right" to me; and their accessories like cables and power products do what they claim. All for a reasonal price. I was never a believer in buying a system all from the same company, but Gilbert is slowly changing my mind on that. (In his case anyway)

The Noisehound is a parallel filter.
Since it is parallel, it removes the grunge without getting in the way of the power flow, which would limit dynamics. Many of the better power condition units on the market like Vansevers are also parallel.

There are some interviews with Gilbert Yeung (the founder) were he is asked why this or that amp or preamp does not lab test well (against the established benchmark or norm). His answer is always that he could have made it lab test better, but then it would not have sounded as good. Tells you something about the "established benchmark" (there may be a better way), and that Gilbert uses his ears, and thinks outside the box to design gear.

Ah! the last thing I did should have been the first.
Installed a High output Ulimate Outlet and did wonders on
the grunge and noise.Really bought it for the surge and lightening protection and was rewarded with cleaner sound.
And yes the Blue Circle power cords are on all my equipment.
Have tried Golden Reference which tighten the sound stage and Harmonic Techs which adds a little grain,IMHO.Thanks
