That DAC you own is a level above the DAC 200 and HQ Player can only take it higher, per my experience. I am new to this whole HQ Player setup and not using the NAA feature. Have you tried the AudiophileStyle forum? I would like to know about this feature (for future) and can post it there. BTW, your system is awesome, yet simple at the same time.
@lalitk ,
I have always admired your setup. Very meticulous and well treated. As for the external PC that goes into sleep, you need to go into settings and choose the power plan to "High Performance". Then you can edit the "power plan" such that when it is "plugged in", it should never sleep, but the display can go into sleep in 1 minute. I suggest that you give that a try and PM me, if needed
To each his own and I am glad that you found what you like. Thanks for sharing your experience.
