Porter Ports or Cabledyne Cryo Hubbell 5362


Just as I was about to purchase 3 Porter Ports yesterday, a friend of mine drew my attention to a new offering on the market, cryoed HBL 5362 by Cabledyne (www.cabledyne.com). Price wise there is considerable difference (as it appears to me): Porter Ports sell of $36 ea. + $12 shipping (for up to 3 units) against $25 each with free US shipping currently being offered by Cabledyne. My heart says Porter Port, but my mind -possibly biased by my friend - says Cabledyne.
Would greatly appreciate the advice from and personal experience/comparison from fellow audiogoners.
thank you in advance.

Cast covers might offer more rigidity and they look cool:

Stone wall plates above with some foil and damping on the back look interesting.

Cast brass might be rigid enough

Cast Nickel might work

Haha, Cast iron available, but that would be magnetic. I'm going to have to check out some examples at the local stores.

Not all stainless steel is non-magnetic the SS82 is non-magnetic. Leaning towards these as starting point and only $12 delivered for 4 (I only need 4, not 8). These can then be damped. Sadly wood insert ones not available for 2 gang, just 1 gang. I've got some dynamat like material from car audio that I may try.

Ordered 2 of the polished cryo'd P&S from Dave:
2 ea P&S 5362A(P) + shipping = $70.00
