Isolation Transformer OR Power conditioner

Spec's on a component aren't worth much unless the spec's themselves offer quite a bit of info as to how they were derived and what the test conditions / parameters were. With that in mind, i remember Psychic forwarding me a link to Dezorel's website. If i remember correctly, these were toroidal based units and inferior to a good quality isolation transformer by some 35 - 55 dB's or so. Since a difference of 10 dB's is equivalent to one tenth the noise floor, and we are talking about 3x - 5x that amount of potential noise attenuation, we are talking about a pretty huge difference here.

Obviously, not everyone wants to go through the hassle of hooking up an Iso the right way, so the Dezorel might work better in such a situation. It is probably far more of a plug & play device than a good sized iso.

Other than that, you need to provide more info on the devices that you intend to hook up to whatever it is you end up buying. I would also recommend checking the archives, as this is a rather common subject that has been covered many times with some very diverse opinions being expressed. Sean

Psychic: I didn't remember the specifics of the Dezorel. The only time i ever saw anything on them had to do with you asking me about them and then some type of business scandal that they were supposedly later involved in.

I do remember you asking my opinion of these units, with which you then provided me with spec's. After examining the spec's, i told you that these looked to be a lower to medium grade toroidal based unit and that they probably weren't worth messing with. When you asked why, i replied that the figures were much lower than what could be achieved with a high quality isolation transformer.

At that point, you forwarded my response back to Dezorel, along with the figures that i quoted. Dezorel responded that those figures would be very hard, almost impossible to achieve. I then forwarded you the spec's on a couple of different Iso's that i was aware of and you forwarded that back to Dezorel. One of those units were the same Iso's that i had turned Lak onto, of which he had two. After Dezorel saw the spec's for these units, that was the last i ever heard from you about them.

Given that i saw nothing outstanding about these units, i pretty much never paid any attention to them. This could be why i didn't recall anything about them or the fact that they didn't use toroids, even though their spec's looked as if they did. Sorry for the confusion if my comments generated any.

Musicfile: I responded back to your email, but once again, you didn't provide the info that i was looking for. I explained what was needed in the email, along with some of the caveats of using an Iso in your specific type of installation. Sean
