Why Can We plug our AMPS directly into wall w/o Worrying?

I use a PS Audio P1200 with my Krell KSA-300S with such good results that I haven't gone back to straight wall connection. I also use the P1200 in 220V mode which benifits from balanced A/C. I know it is pricey, but if you are like me in finding the components you want then it is a final step and a big sonic improvement.

Onhighway61 is right about digital components. I've used a 'scope and a noise sniffer to measure the amount of junk that various high end digital units put back onto the AC lines. In most cases, even for multi kilobuck units, they put out a lot. I use two PS 300's, one for my analog sources and one for my digital sources. Cable TV or digital audio sources are even worse.

Interesting! Once I was lazy to plug in my new EAD DSP700 MKII DAC and I tried it in the wall... The sound of 60Hz was audiable even on small volume of the preamp. Now I keep everything into my Panamax including Bryston 3b-st power amplifier. Panamax is an inexpencive way to connect and protect your equipment against "wall noise" and surges. It doesn't regenerate a clean power like PS300 but it doesn't compromise in power. However if you've solid and new electric wiring in your home, this device isn't necessary. In this case it'll make a sence to get PS300 for small power components and plug large power components into the wall or PC surge protector. I have a horrible electric wires in my appartment and I do not take any chances to plug even TV in there. At least I should have a PC surge protector.

I solved this problem by installing a surge supressor direct into my breaker box....my amp is on a dedicated 12g wired circuit and I'm not in favor of putting in a signal/current disrupting black box...I use Black Mamba power cords and get the effect I want without the linecondioner.

You may want to try Sound Application's CFX. I have recently inserted one into my system with great reticence, mind you. I also had concerns of limitations brought about by "conditioning", but this unit,still in break-in period (reported to need weeks and weeks of break-in), has offered some noticeable and welcomed changes. The most obvious is the blackness in the sounstage. Initially, this character sounded less musical- more hi-fi-ish. Fortunately, as the piece settles, the music amidst the soundstage widens and fills out. The frequency extension has had no deleterious affect even with the amps plugged into the CFX.
