Thanks for the topic, erik_squires...
I have had excellent experience with a version of Furutech's GTX-D (R) receptacle and GTX Wall Plate for several years now. Their non-magnetic Stainless Steel Conductor Spring System "keeps a firm grip yet won't damage male connector blades or their plated surfaces." This has proven precisely so, the mechanism remaining buttery smooth, yet grips solidly. Yes, there is substantial initial cost, but, amortized over time and adding great sound were well worth it. I elect to purchase through The Cable Company to avoid black market goods and also take advantage of their "frequent flyer program" savings. I suppose one must qualify...I've no business affiliation with either company other than the purchase of their goods.
Paying attention to every aspect of building a system leads to gratifying refinement. Onwards!
