This offer is for a package of upgrades for your Lumin X1 to take it to the next level, a Audio Sensibility 0.5M Signature Silver OFC and OCC Umbilical Power cable (that takes 2-3 weeks to get being it is hand made to order in Canada), a Extreme Hifi 2A tuning fuse, and the complete setup to connect your X1 via Fiber Optic connection. Everything you need is here including two sets of transceivers (different transceivers have slightly different sounds), one fiber cable, and TP link switch with SFP port. You will hear (or not hear) a deeper blacker background, better dynamics, more detail, and a deeper soundstage with more space around the instruments. I sold my X1, so I no longer have a need for this package. Thanks for looking and please check my other sales. Free shipping in the lower 48 states.
