Isolation Transformer “Refinements”

Teo, what causes this?

A good sounding filter block (complex LCR of complete device) is one of the great tricks of the trade in power line filtering/enhancement markets.

Medical and pro gear built for such -- tends to be degrading in sonics as much as they filter power.

Wrong kind of lore for the wrong scenario.

Nice. One thing to notice is how low the filtering occurs at.

Another device, much less expensive, which achieves similar results is a series mode surge suppressor such as from Furman or Brickwall which has a -3 dB point somewhere around 3 kHz if memory serves.

Best,
Erik
