I us a Fusion Audio Enchanter - it was a VERY nice and large improvement over other cables I had used (Blacksand, Sororan etc..) - it almost made as much of an improvement as the Mullard 10M 12ax7's.
Aesthetix Calypso Power Cord
I recently purchased a Calypso hear on audiogon along with some nos tubes. I am very pleased it has been a great addition but as always I am looking for that little extra. I wanted to see if any Calypso owners had acheived an improvement with the addition of a better power cord.
