My point (rather badly made I admit) is that in the UK the RCD/ELCB breakers will be set to trip at lower current (15mA) because of Ohms Law and - usually - fast enough to stop you dying... Anyway, the key point is that the preservation of mains "phase" is a debatable issue. I have a "sniffer" that can detect RFI. If you reverse the Live/Neutral connections you can get a lower reading on some gear. However, I can't hear any audible difference in reproduction quality. My conclusion was...leave things alone. Proper earth/grounding is much more important IMHO. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...SB3+Stontronics PSU - Altmann JISCO/UPCI - TACT RCS 2.2X with Good Vibrations S/W - MF X-DAC V3/X-PSU/X-10 buffer (Audiocomm full mods)- Linn 5103 - Linn Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber & Chord cables ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=45195 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
