I'm looking to buy a John Kenny modified M2Tech HiFace USB to S/PDIF transport converter. JKSPDIF MK1, MK2, or MK3. Preferably a MK2 or MK3. Preferably terminated with an RCA output, but will also consider a BNC output connection. I would just need to use an adapter as my DAC has RCA coax. Let me know which model you have, type of output connection, what you are including (box, power adapter, USB cord, RF attenuators, etc...), condition, asking price.
Also willing to consider Audiophilleo, HiFace Evo, SOtM dX-USB HD, Musical Fidelity V-Link 192, Halide Design Bridge, or other quality asynchronous USB to S/PDIF transports
