I have one! An Acme cryo treated, silver outlet for my tube 2 channel system. I also use Mapleshade double golden helix plus speaker wires in that system.

Antique Sound Labs MG S1 15DT integrated receiver
Ah! Njoe Tjoeb 4000 tube output CDP with upsampler
Vance Dickason Titanic 10" sub
Michaura M55 speakers (very much like M22s)

Sounds beautiful.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
