I've got my headphone rig up for sale. It's gone underutilized when I got a HT set up in my living room. Cosmetic condition is excellent for both pieces and both are perfectly functional. Included are the power cords and a short RCA cable.
I am the second owner of both items. The Valhalla's tubes were purchased 2 months ago stock from Schiit with less than 50 hours on them. The Bifrost is Gen 1 with usb w/o uber.
Pick up available in 92122. Asking 240 shipped and PP-ed for the Valhalla.
