Have not tried to connect - as I assume that it is not working.
Currently I am re-ripping my cds at my Mac (db poweramp) with melco d-100.
Have compared the rips with the ones done native to my hdx (new rip copied to the hdx).
The d-100 rips sound a bit fuller and softer. Hdx rips a bit cleaner.
I would be really interested how the rips would sound, when d100 would be connected to the hdx. D100 as transport - hdx doing the ripping.
Do not think that hdx allows an external cd drive? Correct?
