Well, I've decided to sell my beloved Keces 131 MK2. I have the upgrade bug, and nobody can seem to tell me if there is going to be a difference between this and the models I'm looking at, so I just have to try it.
This unit has been EXTREMELY well taken care of - I'm meticulous with my gear. It is a 10/10. It has always been plugged into a Furman conditioner.
It has been upgraded with the gold plated IEC socket, which supposedly adds some clarity and warmth to the sound.
Included is a stock power cable. I will also throw in a 20ft BlueJeans coax cable for another $15 (normally $28 plus shipping).

New this is $440 shipped. Asking $380 shipped to lower 48.
