Quick Q: have you tried using PHA2 with the Zx1 to stream DSD from a NAS - am wondering if it will stream and play the DSD natively. That is without the on the fly down sampling to PCM which zx1 does in order to play DSD files. Thanks!
I've read in this thread that the ZX1 streams DSD natively but converts physical files on ZX1 to PCM first, hth.
