One box music server solution with i2s output

A bit out of my price range. 

Guess I'll keep looking. Thanks.

In that case think you need to look at something more like the Antipodes, but at a much higher price point.

Thanks for the suggestions, but both the Hi-Fi Rose and PS audio units would just replace the Matrix Audio I'm using as a ddc now. They do offer more features, but nothing I want or need. It would not reduce the box count.

I'm surprised that there so few options for a Roon core/server with an i2s output. 

PS Audio Airlens

Hifi Rose RS130 Network Transport has full suite of outputs including I2S via HDMI. I have one on order after having had my dealer's demo unit for a week long home audition. The RS130 is Roon ready and I used it as a Roon endpoint.  Although it has provision for adding internal storage (compartment for installing SSD on the bottom of the unit), I wouldn't categorize it as a server because I believe any storage that was installed would be dedicated to the RS130. I thought the unit demonstrated a marked improvement over my already very competent Bricasti M5, which itself demonstrated a marked improvement over using my Roon Nucleus with Sbooster LPS as server/streamer.  I intend to use the Rose I2S into my Rockna Wavelight.  I will continue to use the SSD installed on my Nucleus for music stored locally. Rose supports a couple of different I2S pin outs, including the PS Audio Format.  In terms of what I consider true Roon compatible Server/Streamers, I know that Antipodes has some very high end kit with I2S.

I'm sure it has been less than a couple of years since I last pointed out how foolish it was to pick your equipment by whether it has I2S or not.
