There has been several internal upgrades since then , I like the fact they vibration control everywhere , even on the SS HD and Teac ripper drive ,3 separate linear power supplies and have done many improvement on the sense app
and ripped my whole Terabyte Flac files very well and checks each file you can change album art as you see fit and the excellent Mundorf MLytic capacitors with. The Nichicon capacitors , gives this unit a bit warmer sound ,with many digital recordings it is a plus , the Audience front row usb cable is really good
their newer reference if you have a warmer system has a bit more detail but a bit cooler balance withthe silver . Ethernet ,and usb cables do count.
