Who has dumped the power conditioner?

Plelko, I think most conditioners lose the pace of the music. I always liked the Sound Application and now the Synergistic PowerCell as they do not.

I second Tbg and the Sound Applcation.

i think it depends on one's electricity and were one lives.
I noticed that power conditioners help if your powerlines are near offices, industrial factories, sites like that.
In third world countries, powerconditioners do help a lot.
In the US, i can do mostly without them. But my friends in Hong Kong, China and Philippines really need them in their system because their electricity is not as clean as the ones in the US.
Definitely, try them out... YMMV

Nolitan - I experienced big improvement in clarity with conditioner (Chicago). It also removed upper bass resonance (lower source impedance?). It is important to pick one with high current output for power amp since amp's power supply takes current from mains in very short narrow spikes of very high amplitude. In a sense every linear power supply is a switching power supply operating at 120Hz with big momentary current demands and conditioner has to be able to supply it otherwise DC voltage drops at peaks - loss of dynamics.

Hi Adwiegert - been away for awhile, so sorry for the delayed response. The Monster unit is what I purchased originally, as in my area we have severe thunder and lightning storms, so a surge protector is absolutely essential to protect the equipment. I chose this particular unit as it has no adverse effect on the sound quality- no different from plugging into the wall directly. It also has the beneficial effect of removing the RF noise, though I always turn off all lights, fans, etc. when listening anyway.

The power conditioners I have tried, on the other hand, have had very negative effects on the sound, as I have described before in other threads and won't repeat again here. One was a PS Audio product, the Quintet, I believe, that my brother owns, and in his area it does make a beneficial difference (he has solid state amplification, however). I have also tried another that a friend brought over, and it was even worse, I forget which one it was, exactly, I think one of the Furman ones. He didn't end up keeping it, either. Perhaps I am lucky to have good power in my area, or perhaps power conditioners just don't go very well with tube amplifiers and/or analog playback, things I have read many others assert here in these forums, and, judging from my own experiences and those of others I know, I have no reason to disagree. I'm not saying it couldn't work, just that it hasn't ever for me, and the effects were so negative that I don't feel the need to experiment with it any further.
