isolation transformer

Thx for all your reponses. What do you think of using silver wire for an isolation transformer? Does it make sense? Or is this just "nonsense"?

I have a T-4 (see picture in my system) that is wired with silver wire. There is (IMO) a 15% increase in sonics. A lot depends upon what wire is used, and where.

I use a xentek ultra isolation transformer daisy chained to a MIT dual iso bank in which my TT and pre are plugged into 1 bank and the digital to the other iso bank. I think Seans comments are right on for my experience. Do not plug your amps in as a well designed amp dosent need them and it will sound worse. Excellent for the times before midnight when the ac is typicaly very dirty. You can find them on ebay for a song and could be a great upgrade for you. Forget about the silver wire type, big, ultra iso with iron core not torroidal is best in my opinion. Be aware theat they have their own slight hum so careful placement is needed.

I am interested in trying an isolation transformer but I am concerned about mechanical noise. The equipment has to sit in the same room as where the listening takes place. Doesn't make sense to me to imnprove the quality of the sound in return for an annoying buzzing. I have had amps with huge transformers and no buzzing so maybe I am overly concerned. Can anyone identify make/model that did or didn't buzz?

Beowulf,
I think all isolation transformers of this nature will produce some type of noise, usually between 60-100 dB. Is it not possible to have the isolation transformer located in a different room within the AC line? See my system set up and check out the picture of the power filtration to serve as a visual aid.
