Hi Tvad, I did not plug the TT-PSU into the conditioner when I tried it, just the other electronics. It still had a very negative effect on the sound when the turntable was the source. I had read that these type of products generally have a better effect on digital sources than analog, and on video sources than audio, for that matter, and my experiment confirmed this for me. When the CD player was the source, the effect was only very slightly positive - slightly better bass, actually, which was a little surprising to me, and a slightly cleaner overall sound. With the turntable as the source, though, it was a drastic difference for the worse. The soundstage was greatly shrunken, and dynamics were compressed quite a bit, especially on the soft end - the softs were nowhere near as soft with the conditioner as they are without it. This was again a surprise, I would have thought it would be the other way around. Loud dynamics were also slightly compressed. The timbres of acoustic instruments and vocals were also not produced as accurately with the conditioner - it seemed to remove overtones is how I would describe it - the timbres were not as rich and complex as they should have been, and are without the conditioner. It also certainly removed much of the ambient noise of the original recording space. I realize that there are many others who have experienced a positive difference with power conditioners on vinyl - my brother is one, actually. He was present when I tried it and was particularly disappointed in the outcome in my system, since it works great in his. His set-up is quite a bit different from mine, though.
To get back more on topic here, I guess my point is that since these type of products will not make a positive difference in all kinds of systems, then one cannot consider them the most important fix for harshness, as some in this thread have suggested. They certainly won't "fix" a bad recording job, or "fix" overly bright equipment. IMO these things are much greater causes of "harshness" than electronic noise, though this is indeed a cause in many cases as well. I do find it interesting that most people I know with low powered amps and high effeciency speakers seem to complain much less about electronic noise in their systems anyway, and almost none of them (again, that I know) use power conditioners. I have to wonder if that has something to do with it. Maybe not - anyone else reading this have any thoughts on that?
