Topic: Transfering vinyl via the SONY PCM-M10 - PROBLEM SOLVED!!!

Weird!  I just tested mine, no hum at all.  You shouldn't have to ground your M10 at all.  My guess is the hum issue is coming from somewhere else and it's affecting your M10's input. 

The only thing I can think of....is your phono preamp and turntable plugged into the same outlet?   Try playing with the outlets and see if that will remove the hum.

That's electronics for you.
I had similar problems in the DAT days. I used the RCA jacks from the turntable straight into the Line Stage OadeMod SBM-1, then the 7-pin into the DAT and the levels & sound were perfect, but I found that I could not run the SBM1 with the wal-wart or I would get a hum. I solved the problem with batteries, and that thing (SBM-1) would EAT batteries, but since I only needed 20 minutes or so a shot, I would use all the "half-used" ones from shows.

It just turned out to be the number of electronics in the chain.

Or ghosts.

Probably ghosts.
