I use the Audioquest NRG Edison receptacle made of beryllium copper. "Audioguy85"
I use Cardas AC outlets. "robert53".
Both are as god as and $100 less than Furutech and Oyaide .
Piss your money away. Hospital grade is all you need. "jerryg123"
Medical grade plugs are great especially for the price but after doing a shootout using a 4 outlet box a basic Pangea came in last followed by a double cryoed medical grade , then a PS Audio and the winner was Audioquest NRG Edison .
