I hate the idea of the removal of an earth.

Many years ago, a friend bought a reasonably expensive Pioneer separates
Hi-Fi system. Turntable, amp, tuner, cassette deck. With all the mains
going to the same 4 way trailing socket and all the phonos connected, it
hummed. making up phono leads with no screen connection at one end - and
trying every combination of connected and non connected ones didn't work.
Got rid of the hum, but ended up with buzz. Only answer was to remove all
the mains grounds except the amp one.

Quad at that time only grounded the pre-amp. Everything else had two
core mains leads. Using 110v mains plugs. ;-)


There is IIRC a 2.2 Ohm ressy in the quad to prevent that problem if a
three pin mains lead of the IEC type is used, and used they are in
"upgraded" QUAD 303's

Or a non standard quad mains via the bulgin
