Power Conditioners: Myth, Magic, or Necessary

Hi
Any power conditioner, cable or transformer (like torriadial transformers) that contain ferrite, sound grainy

Most of my customers have sold off their PC's and conditioners.

They can tighten up the sound a small amount but at what cost?

Congratulations Ernewald! You live in a area where the electricity is as pure and clear as the skies. (no sarcasm intended) I agree with Tireguy, if there are no differences heard with upgraded PCs, why use them. I am also a fan of Cords and Conditioners. I will add one more unit to the mix, since I have not heard anyone mention. I currently use the Tice Solo Power Conditioner and the Tice Solo Enhancer.
The Tice Enhancer has no filters nor can it remove anomalies or spikes and surges from the power. What it improves, is the depth and dimension of your soundstage. You have heard of cryogenics I'm sure, where a material gets frozen. Tice uses the complete opposite technology. Tice uses High Current Electricity to treat thier component materials.

I have my DAC, DIP, Transport, and Power Conditioner plugged into the Enhancer. My Amps are plugged into the Power Conditioner. I have tried many combos and this worked the best on my system.

I mention this passive unit as a tweak instead of Power Conditioners that you may not have a need for.

The Tice 3C power conditioner is transformerless. It's their latest design, and according to their hoo-ha, is a great improvement over the earlier ones. I haven't owned the earlier ones to compare. All that I can say is, the proof is in the sound, which is absolutely phenomenal - a drop-dead when drop-in difference. The Panamax I owned before is an overpriced power strip, and a lousy company to deal with, to boot.

My experiments
I live in a rural area, about 50 houses around my home. About 300 yards from my house is the HQ of local cable, telephone, and the internet provider’s office.
My home theater system consists of AVA FET valve hybrid amplifier, an omega Star pre amplifier, 3 channel Power amplifier, Onkyo DVD player, Omega star DAC, EFE speakers, Monster 1000 HTS power surge protector and conditioner.
The picture quality and audio is lot better in the late night. .
I assumed the sub optimal audio and video in the day time is from power polluted power and cable TV signal.

I am interested in getting the audio quality during day time and evening.
I followed some of the suggestions
Cleaned the connectors, RCA plugs, metal prongs for the power plugs, speaker terminals etc with De Ox. Separated and spaced the cables, ICs with dowels, and foam spacers... Elevated all the cables from the carpet using Jeweler stands made up of ceramic about 4 inches from the ground.( available at Wal-mart during Christmas season.3 $).I connected
Digital and audio components- to different outlets. I purchased a separate digital power filter with 4outlets for 120 dollars from virtual mode to which I
Connected Cable TV box, TV, DVP player and DAC)
The audio portion improved with less background noise. But video image remained the same.
The new Cables, Composite for the video from better cables com did not help much, component cables from ZU megular improved the color saturation .Fine tuning with Avia video set up disc did not help much with graininess of the picture other wise did improve the color balance. I tried video coaxial cable noise filter and surge protection filter on the Monster 1000.It attenuated the sound.
I purchased a video noise filter from Virtual mode for 6 $.it improved some .Parts express also sells one for 9 dollars.

Using ferrite core on the cable company co ax cable made the picture dark. It did improve the picture a little when attached to the power cable TV digital box.

I checked the RF with a portable AM Radio tuned in between stations. The cable TV box and the DVD player produced more noise. I separated Digital and analog components on the rack and the Cable TV box went on the Top of rear projection TV away fro the analog components.
There is a definite improvement but not in the same league as the Picture at late night or the very impressive audio at mid night.
I purchased Blue circle 86 noise hound/pillows mark2 for 100 dollars each including shipping from a dealer at audiogon.
Connected them to the power outlets directly they do improve, no back ground noise, clearer, better definition, bass .more closer to the sound and video during the day and evening but not the same quality at 2 AM.
I do not want to change the power lines as I live in a rented house, but I will change the power plugs later.
I do not plan to spend S1699 for audiomagic magic stealth.
I am lookig for a cheaper solution.
Will continue later with my further experiments

I do know from experience that, as others above have attested, different components will benefit to differing degrees from AC power tweaks. Your amps simply may not need this treatment to sound good. Or, your system (or ears) could be failing to inform you of the differences, which can range from large down to subtle in nature. And then there are always the matters (as was also mentioned above) of *which* PC you're using, and how contaminated your AC is in the first place.

So I'll just bring up two things additional here. One being that, other than your AC quality straight out of the wall, there's also the issue of stray environmental RFI/EMI to be protected against, and the possibility exists that in your particular location and system, this may simply not be a big problem. The other thing is that in many instances, it can be source components that will reveal the most benefits from an upgrade PC, so before you sell the cords, you may want to try them out there instead just for grins.

I have found that filtered power, and especially balanced filtered power, can and does make a positive (though not life-changing) difference, particularly on my digital front-end, so you may still want to try a PLC out. But after all is said and done, I agree with Tim and the others - if you can't hear an improvement, then be all means get rid of 'em and just enjoy your music!
