For the DSD-heads out there, Linux does not yet have a driver that can handle DSD256 and above. That means that for the HQ Player upsampling crowd, this is a no-no for now. Windows is the only way to go.
Windows 2012 with Audiophile Optimiser is Core mode is Exceedingly good and now that people are getting this to work with HQP, many have found their Nirvana.
AL, a streamer just streams data, no storgae. Add on storage and it becomes a Server. That is why Aries will become a Server with the addition of the USB HDD input. It will also stream from a NAS and do the Tiday, radio thing. it will not rip CDs like many Servers do, including the expensive buut phenomenal Memory player made by the tempermental genious Mark Porzilli.
The MemoryPlayer has lots of proprietary tech like Read until right(RUR), IDEAS (jitter reduction), D2D, 64bit playback and Jukebox.
