Will trade Westone Um3x RC for Sound Devices headphone amps MM-1 or HX-3 as well as Ray Samuels portable Amps. Um3x's are in practically new condition, I have only used them for several weeks. 20 hours total listening time. Guaranteed functional. Any other portable amps will be appreciated. Thanks for looking.
