DAC compatibility


Hi all. I'm encountering a problem that does not have a satisfactory solution. I own a BSN 130 which functions fine using the internal dac. I recently acquired a Topping D90 MQA DAC to receive the USB out of the BSN. I get a lot skips when playing MQA files. Otherwise it seems fine. However, my macbook seems to like the D90--no issues playing back MQA streams via Roon, BluOS, Tidal.

Based on what I've read about this issue, the solution inevitably becomes: use optical or digital coax or don't play MQA. Topping blames BSN and vice versa. That drives me nuts.

Now, I read something interesting about BSN UBS: it doesn't love 'desktop' DACs because of its unique linux USB architecture. Also, desktop dacs only like CPU/laptop USB. 

It may be a Topping specific issue. I swapped in a Dac magic 200 and all was fine. How do I sort this out? Is there any truth to the USB compatibility argument? 

I am considering going to an integrated dac/streamer. 

Thanks in advance for any input or solutions.

I thought USB was a standard so it doesn’t make sense to me that either of your devices wouldn’t like the USB out/in from the other.  This link discusses drop outs from MQA but via Roon to an external DAC.  Nothing else about dropouts other than Roon though.  Seems like a BSN issue with MQA.
