John: I have not used the Jena Labs, but do use exactly the same receptacle that is sold by Alan Kafton at Audio Excellence for $55 (about half the price of the Jena). I shouldn't say exactly, because Audio Excellence apparently subjects the receptacles to a double cryo treatment. I have no experience with the Wattgate, but do have experience with a number of other stock receptacles, including the Hubbell hospital grade 8200/8300's, which were the best stock receptacles that I used. The cryoed Hubbells are in a totally different league than the stock units, and I submitted a review of one that is in the review section here. I actually just received 2 more yesterday which I slotted into my line conditioner, and they are pretty spectacular for $55. I am actually very cheap when it comes to audio and never in a million years would I think I'd be recommending a $55 receptacle, but it is, as Bob says, just like a component upgrade and very much worth the expense!
