Lumin U2 vs Aurender N200

This month’s Sterophile raves and raves about the iFi Audio NEO Stream. It’s $1300! 

Once again, a reason to not trust everything that you read. Especially by a professional reviewer.  I demoed a NEO Stream and ended up returning it because it sounded no better than the (noisy) PS Audio Bridge II card. Then when the Lumin U2 released, I wanted to see if I had gotten to the best possible digital SQ with my fiber optic LAN. The U2 proved that a streamer can make a massive difference in SQ when compared against one another. It was a larger impact to overall SQ than when I upgraded to the current Ayre KX-5 Twenty preamp. That says a lot and I'm certainly a believer now that streamers matter. A lot.

The U2 doesn't have an external PSU.  It has a built-in linear PSU.
