Guys,
I don't see the requirement for a digital input. I am totally in the digital realm with file playback through a MacMini (dedicated and optimized for processing digital files) and external DAC.
The appeal of this unit to me would be the proverbial "one box" solution for digital playback. If I can accomplish that with the HAP with a simple interface capable of playing "all" current file formats why would I want a digital input? Certainly not to feed files from my MacMini again.
Also, I have no interest in processing files from a transport (ie spinning silver disc) since all of my content is on external hard drive with the Mac.
My only concern is adopting the HAP without taking a step backwards in sound quality. If I can equal or better my current DAC, the functionality of the HAP seems like a no brainer to me.
Looking forward to auditioning the HAP on Sony's 30 day full refund trial.
Best,
Dave
