Power cables for ARC Reference 75

David,
If you like the sound of your old cords, why not just get a 15 to 20amp 'adapter'. Shunyata make good ones (15 to 20amp or vice versa). I've used them ~ fit snuggly, good contacts and reasonably cheap too.

I believe ARCs are using ever since ~ to date, 20A connectors on all their equipments.

SP8, SP10/mkII, SP11mkII, REF 3, REF 5/SE
D115, Classic 150, M 300, REF 600/mkIII, REF 150

Perhaps not all, but those I've owned in the past (as listed since early '80s-current) use 20A connectors. It puzzles me even more if they are inconsistent in their application.

It is a hindrance at times with ARCs that you can't just swap your favorite PCs around. I don't think that it is power rating related, as I've had some behemoths from Jadis and VTL last time that do fine with 15A ones. I guess more of a corporate choice, even their cdp and pre's utilize them.

Just looked up pics from webs, and you are right, most/all their LS line stages use
what look to be 15A connectors. Should have used in my first post, 'IME or mostly'
instead, sorry.

As for the '80s SP pres, couldn't even be sure myself whether they were using 20As or
non detachable types--my memory fails me, further, aftermarket PCs were not in trend
back then so we just use whatever it came with, those were better days.. ;)
