Wattgate 5266i Black Edison AC Power Connector
Wattgate 5266i Black Edison AC Power Connector is rated 4.5714 out of 5 by 7.
Rated 5 out of 5 by from This review is for Wattgate 320i and 5266iAn audiophile friend of mine turned me onto making my own power cables for a fraction of the price of premade ones, so I figured I’d give it a shot. He has a few “recipes” for quality cables and they all started with these connectors. Quite frankly I just wanted a low gauge high quality cable for my power amp (Adcom 5802) so I wasn’t interested in “braiding” my own, standard SJ type cable would be fine with me. I don’t have a listening room and the majority of my equipment is Mid-Fi at best with the exclusion of my Eggleston Andra “clones” (Dynaudio drivers, subs, Scanspeak Tweeters (I think) etc etc).Now that you know what my goals were and what I’m working with, let me tell you about the connectors. I originally bought 2 of each of the connectors and 25ft of 10-3 Carol from PE. Come to find out, 10-3 won’t fit unless you remove the inner wire clamp or strip the wire past the rubber housing. This was a No-No for me. I wanted the inner clamp to interface with the outer rubber housing. Since I can be impatient at times, I ran to the local hardware store with my plugs in hand to see what would fit. Turns out that 12-3 works *perfectly*. Why I even thought I needed 10-3 in the first place was beyond me. Even 12-3 is over kill IMO. The inner connectors are metal on metal and clamp nice and tight. The 4 other housing screws are into plastic, but you could feel when the plastic was starting to stress under tension and that’s when I would let off. Over all I’m very happy with my purchase and I’ll be making more when I upgrade my components further.For reference- I would strip the outer casing at about 3.4cm and the inner wire about 1.5cm. That would make it so the outer clamp would interface with the black outer tube (in case someone pulled the plug out by the cord and not the plug) and no stripped wire would be showing when they were put into the “clamp holes”.

Rated 5 out of 5 by from Rugged and FunctionalThis seems to be the go to product for most audio applications; I highly recommend the Wattage right angle adapter combined with this Wattage Edison connector to enable any angle of approach with thick power cables. The Cryo feature of this product is important to the smooth flow of electrons and does improve the delivery of power, and sound accordingly.

Rated 5 out of 5 by from Favorite AC PlugThis is a very high quality AC power plug, so much better than what is sold at the local home center.

Rated 5 out of 5 by from solid designvery nice tight grip on wire ends without damage, easy to use. If they could just make a clamp that centered the cable perfectly it would be an even greater value in the world of silly priced plugs.

Rated 5 out of 5 by from Wattgate 5266i-BLK Edison Connector BlackSimilar to my review of the Wattgate 320i-BLK IEC Connector Black, this connector also provides a "gas tight" connection. It is worth making your own power cables. I used 13 gauge 99.9999% pure copper "Neowire" and made a 2' cable. The cable adds noticable positive tonality to the music, readily noticable upon comparison to even hospital grade cables.

Rated 2 out of 5 by from Over PricedPurchased these to make power cables. I think they are over priced, it's that simple. I saw nothing that warrants the price.
