"Would I be getting the cord's full effect on a player without a ground prong in its IEC inlet?"
There should be no audible/electrical issue due to the ground wire not being connected to ground at the IEC component end. Some folks may be concerned about ground conductor resonance due to it floating on the component end, but I've never audibly noticed such a thing.
OK, thanks for your response. I suppose I can just find out for sure by trying! Best regards,
Hi JB Coleman,
As you know, the VH Audio Audio AirSine is a very advanced design. One aspect is that the externally spiraled ground wire of the power cord is effectively isolated from the current carrying conductors, so I reckon any effect if any (no effect, IMO) would be well below the system noise floor. No worries ;-D
You might want to upgrade the stock IEC inlet of the Marantz SA-11S2 with an Oyaide Power Inlet R (platinum + palladium plated phosphor bronze contacts) IEC inlet to mate with the Oyaide C-004 IEC connector of your AirSine. Since the SACD/CD player is not grounded, just ignore the ground pin of the upgraded IEC inlet. In practice, having a ground pin might help better secure the IEC connector within the IEC inlet, so there's only good things to gain by the upgrade. BTW, a DIY project has also been documented for the Marantz SA-11S2.
See link below for easy IEC inlet modification instructions for the Marantz SA-11S2:
Thanks, Duster. A characteristically generous response. Best,
