balanced power

That was a good reply Sugarbrie,thanks...

So, if you were able to run 240V equipment in the USA, [changing the outlet receptacle, and running a 240V line to it], would it sound better, since 240V is balanced...isn't it?

is this the same concept used in fully differentially balanced amps and pre amps?

Yes, American 240V is balanced.

Some equipment likes balanced power, some indifferent and very few are not compatible. For example, the SFL2 preamp was a completely different animal when fed balanced power, it loved it.

A simple isolation xformer won't do. You need a step-down with dual cores. Also need to derate the output by half. A 240/120 can be wired for balanced output if you put 120V in. I went one step further and used 240V.

Just an FYI... Blue Circle will custom make a balanced Music Ring to step-up or step-down voltages with the required plugs, etc.

I assume others companies will also ??? If you are a PS Audio fan, you could check with Paul McGowan.
