I've had a bit of a look back through this thread, and haven't seen this mentioned, but...
Maybe a range of good quality cables for TOSLINK, RCA, Coax, etc connections? My amp (or was it the DAC??) came with some workable, but ugly, RCA cables. Wouldn't mind having the option of perhaps a few nicer looking cables with maybe textile housings, short to medium lengths.
