Don't site a power amp immediately below a turntable: good advice?

[Coda II]

To what extent is a cartridge likely to pick up interference from, say a power amp's transformer being close to it and how close is close?

Just another in the 'is it true, is it a myth or is it just blown out of proportion' things.

depends on what type of power amp it is!

Generally speaking, yes, it is good advice, especially if you are using a low output cartridge.

Depends on the amp, the phonostage and the cart.

I'd say simply that if you can hear hum induced from the amplifier you need to move it, or the TT.

Most power amps use toroidal transformers and these don't radiate appreciable field unless massive. Metal screening on the amp and phono stage also helps.
A good reason to avoid acrylic or other non metalic encloses - certainly for phono stages.

Do you mean that glass type acrylic or that plastic one? ;-)
