I have every intention of auditioning the Air Lens in my system when it becomes available. Having said that, I’m somewhat concerned about its connectivity compared with my Matrix. In viewing the rear panel, I see that it seems to accept a USB A connector and the Matrix takes a USB B connector.
I’m bringing this us because I’d like to be able to continue using my somewhat pricey (to me) IN-AKUSTIK Reference High Speed USB 2.0 cable.

The way my setup works now is that there’s a USB cable running from the Nucleus to the Matrix and then an I2S cable running from the Matrix into the DirectStream DAC.
I’m wondering how the input/output connections differ with the Air lens.
You’ll then need to hook up the AL to your Ethernet. You’ll probably have to do some sort of configuration on the AL so that you enable Roon on it. After that Roon will see the AL, you’ll need to follow the normal setup in Settings → Audio in Roon, and then you should be good to go.
I remember @Paul saying in one of his videos that he had exactly the same setup I do (Nucleus, Matrix, DSD) and said that the Air Lens sounded much better in his system than the Matrix.
