I purchased an original (not upgraded) PS Audio Perfectwave DAC MKII used. The unit is probably about 1 1/2 years old. I’m having an issue with the Native X setting. After playing for about 5 to 10 minutes at the Native X setting, the sound stops for no apparent reason. The unit is still on and my amp and speakers are ok. At this point, when I cycle through the other settings (i.e. 44khz, 96khz, Native, etc), they all work and I have sound, but not the Native X.
When I turn the unit off, the back switch to off, wait 10 seconds and turn it back on, Native X works, but for another 5 minutes or so and again the same problem (i.e. no sound). I tried both USB and Coax inputs and same problem with Native X.
I installed a previous firmware version 2.4.5 and also reinstalled the current version 2.4.6 and in both versions, same problem. So I think the Native X digital lens may be bad. Music is just not the same without Native X.
I plan to contact service support on Monday, but wondering if anyone has any insight or can offer some suggestions to try, or perhaps had a similar issue and can chime in. I heard PS Audio has great customer service and is responsive, so I hope it will be fixed under warranty if indeed it has a bad digital lens.
