I'm looking at buying a HAP-S1. I have one on loan, but have found some quirky functionality issues - all of which could likely be resolved through a firmware update.
- Why no variable output option? This would make an excellent standalone preamp, but the internal amplifier isn't all that great. - Why no NAS streaming support? I can't fit all of my music on a 2TB (max capacity for this player) drive, let alone a 500 GB one. I don't want to use a hub for an external drive, and I use the USB port to feed my DAC. - Tidal, Pandora, etc... support? - Airplay?
