Well Randy's (OP) link shows $750 for those and they aren't TR receptacles. The sillites that Jumper links to are less than $20.00 and are removable with two screws. The other you need a special tool to remove it for $150.00.

but then everyone ran over for show and tell in the AV arena,
where reason and logic haven't ever been permitted......
"The speaker cables for Kharma speakers.
"The Enigma Signature Loudspeaker cable is the upper-end
loudspeaker cable based on a huge number of various diameter
pure silver-gold conductors and is terminated with special high
quality pure silver-gold Kharma spades, realizing a high-quality
one-material conductor-termination-circuit. Besides the conductors
are equipped with the Kharma Advanced Core Treatment 1.0
(ACT-1.0) and the Kharma Proprietary Insulation 1.0 (KPI-1.0).
In addition a massive vibration isolating tubing reduces the vibrations
to a minimum before reaching the pure silver-gold conductors.
Furthermore the conductors are placed behind ultra effective shielding
to protect the signal from unwanted external electromagnetic interference.
All this leads to a crystal clear and very powerful cable, with extreme
revelation of the smallest detail, infinite resolution, enormous dynamics,
sweetness, air and a very realistic and transparent, holographic soundstage
with an overwhelming musicality.""

my original post was that i was just marveling at the outlets...
i was thinking they looked pretty cool, as for access to the box,
bring your forceps. if i had to put these in, i'd put a 4SD steel box,
and plan my wiring carefully.
alas, there aren't as many customers willing to pay $300 per outlet
for the device, not counting the labor, as there might have been a
few years ago....
