Who has dumped the power conditioner?

Getting back to the original topic, I have tried a couple of different power conditioners in my system, and both were absolutely awful sounding, especially for LP playback. They weren't nearly as detrimental for CD playback, though the sound was still compressed, both in dynamics and soundstaging. I won't be trying another.

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.
