The HDX is wonderful. I think it's very underrated. Out of all the dedicated "music file" players, it's my favorite both in terms of musical presentation and reliability.
NAIM HDX
Anyone have experience with the NAIM HDX? Just spoke to a retailer who said the sound would be 8 times better than my Rega Planet CDP. Had been thinking about a Sonos into a decent DAC, which would be much cheaper, but am beginning to rethink... won't mind spending more if the sound is clearly superior.
