Unfortunately not that robust. In fact not strong enough to securely hold the original SR Galileo power cords without a support such as the Furutech NCF Booster
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.
