Synergistic Research UEF Receptacle Grip


How strong is the grip on the Synergistic Research UEF compared to Furutech GTX R NCF or PS Audio Power Port?  Any sound comparisons appreciated as well.  I like SR products, but I need very strong grip for my power cables and the SR UEF looks like a spec or industrial grade outlet that's been cryoed, so I wonder about the grip.  Thanks.
