Replacing/Upgrading AC Outlets

The cryoed Hubbell 5262 that Virtual Dynamics is doing has every right to be an excellent receptacle, although I haven't heard one. It is simply a 15 amp version of the Hubbell 5362-the only difference is that the 5362 will accept a 20 amp plug. Other than that, the 5362 and 5262 are built to exactly the same standard and are identical.
The Hubbell 8300 has a different face material and its contacts are nickel plated; apparently the nickel plating will give the receptacle a slightly more forward presentation. Some will say that the nickel contributes a "brightness".

The other question relates to the actual cryo treatment. The World Power receptacle is subjected to a longer than usual cryo treatment; whether this translates into better performance, I can't say because, once again, I haven't heard the VD receptacle. The VD receptacle also offers some form of contact enhancing treatment from what I remember, and the World Power comes "burned in" to substantially reduce your "burn in" period.

Like everything else in life, you pay your money, you take your chances!

Hospital grade is more than good enough for any hifi application. So-called “audiophile receptacles” are just a euphemism for “sucker receptacles”. By the way, spec-grade is more than adequate and well worth the 10x price of your common $0.79 receptacle. Beyond spec-grade, the law of diminishing returns applies.

Appropriate name for the guy resurrecting a thread from 2002.Is your name Rip Van Winkle by any chance??              
Just to goose the thread I used to use Pass & Seymour duplex. Recently I decided to 'upgrade' to Furutech duplex. And bought 15 GTX-D, 10 gold, 5 Rhodium.   (they were on sale... LOL) 12 installed. three to go.
They were cheaper than buying a Audio Quest Niagara. LOL(I already own both a PS Audio P-600 and a Furman REF20i So most of the new duplex went into those devices.)

The Hubbell 8300 has a different face material and its contacts are nickel plated; apparently the nickel plating will give the receptacle a slightly more forward presentation. Some will say that the nickel contributes a "brightness".

The old stock Hubbell 8300H Hospital Grade with the compact slim body is the best neutral sounding of the Hubbell outlets in my opinion. It has non plated brass contacts with a non plated brass supporting back strap. Hubbell stopped making this receptacle many years ago.

The Hubbell 8300 Hospital Grade 20 amp outlet that is described in the quote above sounds like, maybe, the deep body outlet. It has nickel plated brass contacts and a nickel plated brass supporting back strap. Only a guess though this the outlet I described.
Here is the 15 amp 8200 Hospital Grade outlet. Note the deeper body. Also note the heavy duty square center hub for supporting the duplex cover plate. Typical of the deep body heavy duty outlet. The compact slim body will have a heavy duty round hub.

The newer Hubbell Hospital Grade 8300H and 8300 outlets have nickel plated brass contacts for corrosion with a galvanized steel supporting back strap. These are garbage IMO to feed audio with. Avoid steel supporting back straps. Same for the nickel plating used on the contacts for corrosion protection.

This is not an old stock Hubbell 8300H Hospital Grade outlet.

Note the galvanized supporting back strap.
