Pangea AC14XL removeable ground plug

I bought this Pangea AC14XL to replace a Cardas for two reasons.  The primary is the removable ground plug.  The ground humming noise from my Passlabs X150 is very annoying.  I tried different products and none of them work perfectly, the only effective way Passlabs support advised me was cheater plug which works but not really happy using one with Cardas power cable and Passlabs amp.  So the removeable ground plug solves the humming issue without using cheater plug.  The second reason is the deathgrip.  Cardas power cable is stiff so it gets loose over time (mine gets loose on amp end)  I like this cable being securely connected.  The cable is new so not ready to judge sound yet.  The initial impression is neutral.

Does anybody use power cable with removeable ground plug, and what is your opinion on this old but persist topic; and Passlabs owners do you get ground humming noise?  I have used X3, X250 and X150, all has ground humming sound.  If so, how did you solve it?  Thanks

Oddly enough, Parasound puts a ground lift switch on their Halo amps.  
These ground lift switches typically just isolate the signal input ground from the chassis ground.

Tried the following methods this weekend

1. Disconnect the turntable and preamp individually and both
2. Disconnect all other electric items in the room (a light and a small frig), also disconnect all electric items from the room next door and the bathroom nearby (only a night stand light, alarm clock and a LED night light).  I also replaced the ceiling fixture lightbulb with LED.
3. Tried EBtech on preamp and turntable

well, none did any difference, I guess I will continue to live with no ground pin.  I like this Pangea AC14XL cable, the grip is tight, the cable is bendable and I don’t hear sound quality loss from the Cardas it replaced and a lot cheaper than Cardas.  Don’t mean to imply this cable is equal or better than Cardas, just I can’t hear difference in my system with the type of music I tested so far.

thank you all for your suggestion and feedback.

Did you try the Ebtech on the power amp?
