Who is fooling whom ? Stick to the topic, pls.

Hi.

First off, have you used any so called "isolation transformer" at all? Or just hearsay.

Years back, I did use one, 1KVA custom-built like a tank, with static shield, & housed in a large shielded metal housing, exclusvely for my audio gears, feeding the dedicated power lines direct from my house fuse panel powering my gears only some 20ft apart.

Frankly, I am NOT impressed at all by its sound. It slowed down the sound bigtime & put up a thick veil over the music. The music came back to its life & rhymthm instantly again after the isolation transformer removed out of the system.

Don't overlook the ever exisiting parasitic capacitances btween the primary winding of the so called "isolation" powerline transformer & its secondary winding. It is the series-coupling capacitances plus the shunt-wire resistance/inductances of the ground wires of the equipment effectively form a highpass filter for the EMI noises ride through.

You believe what those power hardware vendors told you? I did but today I don't after this costly experience.

Of course, one does not need to drop a huge bundle for exotic wires, but I would not use THHN, XHHW, RW90 cheapie types building wires to power my audio rig.
