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


hi all.

considering power conditioners for my system, and am stuck on why I can plug my krell amps directly into the wall without worrying about line surges, dirty power, rfi and similar evils... why is it so much more important to get 'clean power' to my other components and to 'protect' them, but so many people advise plugging the most expensive part (of my system) directly into the walls? are power amps somehow impervious to dirty lines and spikes? someone help... with my setup, i could just get a ps audio 300 or mit z center or chang iso 9600 for the components and go the amps directly into the wall, or i could get a more expensive device (ps audio 600, chang ht1000) that includes power conditioning for the amps... thanks again all for your reponses... -

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.

Hello Baz...I had my BAT amplifier plugged directly into the wall for many months. When the "thunderstorm" season came around, I found that my amp was popping several 10 amp fuses each time there was a quick "on and off" 1-2 second power outage. This really became a pain since I was replacing fuses several times a week plus I became quite concerned about the welfare of the amp. A good friend recommended trying a VansEvers Unlimiter with the amp. My BAT has (2) power cords which have been upgraded to BMI Whales. By using an unlimiter, I realized that I would have to use another Whale from the wall to the conditioner requiring 3 power cords to run this amp! I figured that there would be a loss of power also since both amp cords were pulling from 1 conditioner cord. Well...I guess that serves me right for figuring. The amp sounded MUCH better with a substantial increase in power and bass response. As a by-product, only 1 fuse has blown. VansEvers states that the Unlimiter does not limit power. I must agree with that statement given the all around upgrade in my amps performance, not to mention the peace of mind knowing that my amp now at least has a degree of protection. Try one...
