Post Subject: Isolation transformer and PP3000Posted by Romy the Cat on: 12/25/2011

I know it does not make any sense but it looks like the power line before PP3000 does matter. I took today my large 3kW isolation transformer and place it between my dedicated line and PP3000. I lost my lower bass, simple as that.  Yes, the isolation transformer did wonderful thing with noise that PP3000 returns back to the power line, it just simply illuminates it but who cares is it ruins Sound. So, what I thinking: if the noise from switching PS is so effectively taken care by isolation transformers then why do not use the isolation transformers on my house power consumer and let the PP3000 to run from my dedicated line as I have it now ….but to have the house isolated from dedicated line via isolation transformer. Or perhaps I just need a better quality isolation transformer to run on the PP3000 line? It truly does not make any sense as PP3000 shall buffer everything that happens before it. I might understand if some kind of ultra HF noise (we are talking 100s Meg) would pass across PP3000, in fact it will pass across anything, but why PP3000 does not override the sonic problem of isolation transformer?
