A two prong only factory plug (not one that is cut or broken off by the end user) or a proper isolation transformer setup inside the linear power supply without any center taps to ground. One of the best temporary tests (and I do mean temporary) to find what might be causing ground loops, is to use one of those plugs from the hardware store that takes a 3 prong plug to a two prong plug. These are harder to find now because homes have been required for years to have 3 prong outlets. By placing the plug on the end of the cord (as long as only one item of equipment is causing the problem) and plugging it temporarily back in, one can quickly find the equipment causing the problem. There are commercial products with will isolate ones equipment from ground loops as well as almost any lightening strike also, such as a 220 RGPC Sub-Station. This unit uses two hot phases to make 120 for ones equipment. There is no ground so there can't be ground loops and this eliminates any path for lightening to ground as well making it high unlikely that lightening would seek that route. The added bonus is additional available current headroom and the near elimination of line sag as two phases are involved. In most households, both phases sagging at the same time is rare. -- iPhone *iPhone* 'Last.FM' (http://www.last.fm/user/mephone) Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, Vandersteen Quatro, VeraStarr 6.4SE 6-channel Amp, VCC-5 Reference Center, four VSM-1 Signatures, Runco RS 900 CineWide AutoScope 2.35:1 Living Room: Duet, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Kitchen: Squeezebox BOOM Bedroom: SB3, GFR-700HD, Thiel 2.3, Second Boom Home Office: SB3, NAD C370, two VSM-1 Home Gym: SB3, Parasound Vamp v.3, Thiel PowerPoint 1.2 Mobile: SB3, Audioengine A5 ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=59264 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
