I use a Lumin D2 in my system and think it's an excellent performer. I use it with a 20TB Synology NAS and an iPad for wireless control using the Lumin software interface. I believe the X-1 would perform at least as well as the D-2 and probably even better.
Sorry, I don't have any experience with the PS Audio Direct Stream.
Thank you so much for your reply.
I am presently using a Bryston BDP-2 with my hard drive attached to it and then to the PS Dac. The Bryston and the hard drive works flawlessly.
The Lumin would stream line my set up. I am hoping the sound quality will be as good or better than the PS Dac.
No way to compare both. So I am trusting the on line reviews (risky) and hoping some Audiogon members can reply.
