Why not just use a digital input on the back of the 134 and use a digital source e.g. computer, sonos, etc.? I owned a 134 and the D/A convertor within is a very good D/A to use till you decide you want better. As far as cable, that depends on budget and your ear. Try a few demos from you local dealer. Contact usedcable.com and see what they have in their lending library.
