about ready to dive in to streaming... PS Audio AirLens vs Aurender N10?

What features?

I think the Aurenders can do a lot more than AirLens.   You can only do Tidal and Qobuz through Roon on the AirLens which would be a no go for me.  

The N10 is a full featured streamer that has native Tidal and Qobuz apps built in.  It also has internet radio and can accept internal SSD.    

If you are firmly distilled down to just these two choices, then it’s the AURENDER for me.

if you are willing to consider other options that are peers or better - as contenders and no pretenders - ,then think MOON by Simaudio

You can use Mconnect to stream Tidal and Qobuz with the AirLens. Not the best method by far sonically or from UI perspective. Roon is your best option with it but it’s a subscription service. Advantage of the AirLens combined with the PS audio DAD is the i2s interface if you buy into PS Audio clams. 
 

Aurender N10 has a superb clock and uses caching which helps in getting a signal as jitter free as possible. Conductor app is easy to use but there’s no Roon with N10. Best connection between the N10 and the PS Audio DAC would be the AES/EBU interface. 
 

I never owned the AirLens or the N10 but I did own a PS Audio DSD MkI and used Aurender N200 with it via AQ Diamond USB cable. I still have my N200 with no plans to change it but the PS Audio DAC is gone.
