Are There Roon Ready I2S Streamers?

I'm using an iFi Zen Streamer through a Matrix Audio X-SPDIF to connect I2S to my DAC. There's always a trade off. I've added another device in the signal chain (and associated cables) but so far the improvement over USB is worth it to my ears.

Next time around though, I think I'll be looking at a single box solution -- streamer/dac.

I have the Sonore Signature SE and tried using the Matrix DDC to I2S and really did not notice the big change others have.  The Sonore is super sounding.  That being said I think I will try the PS Audio AirLens when it comes out in the next few months.  Its ONLY got an I2S and uses the same isolation their beloved SACD player does.  Supposed to be around 2k.  

Try a Matrix X-Spdif-2

This will convert USB to i2s.

I just ordered a Holo Audio Red streamer and it has i2s output with configurable dipswitch settings.  $800.  At that price it’s worth trying.
