isolation transformer


Hi, I would like to hear from fellow Audiogoners what they think whether or not the use of an isolation transformer for the front end gear (CD player/DAC/Phono) is worthwhile.
According to a well known Swiss manufacturer/distributor the use of an isolation transformer has profound effects on sonics (more detail, better bass, etc.). These effects are more pronounced when using silver wire for the transformer. Do you agree with these statements? What would be better: using a smaller transformer with silver wire (say 200VA) or a bigger one, using copper wire (1200VA)? Thx in advance for your response.

I use a 1 KVA and a 3.7 amp Topaz on my Digital gear with great results. But after checking out Lak's system I'll be dreaming of power tonight. really nice set up Lak very well done.
George,
The T-4 is really sweet. One has to hear and demo it to really appreciate it. Great for front end equipment.
I watched Ebay and other sources for about 1.5 years before I located this T-4. As it happens I had a “want to buy” ad on Audiogon for about three months and a member sold it to me.
