Streamer recommendations

I recently got an Eversolo A8 streamer/DAC and really like it. Easy set up, supports Tidal, Qobuz, Spotify and others. Also can stream from USB devices or, an internal SSD up to 4tb (not included, user installed). Sounds great to me (I had tried the Cambridge Audio CX100 but sent it back as it was hard to use and sounded too bright for me). At $2k I felt the A8 is a good value. 

I never used dCS Mosaic but I can say that Aurender Conductor and Lumin app are completely different animals. Aurender provides a much better user experience than Lumin, it’s more user friendly and has better features. Lumin redesign is way overdue. It’s just not good.
My recommendation, based in my own experience, is to use a separate dedicated streamer.
Or if you want top notch UI/UX with dCS go with Roon but that in most cases comes with a slight sacrifice in sound quality…you need to test it and determine for yourself.

I love my Naim Uniti Nova - they just released a new model (Nova PE) with more power.  Roon ready, and great high res streaming internet radio, plus Tidal and Qobuz, Spotify, etc. - I ripped my CDs and have purchased hi res digital I play through Roon that sounds amazing through the Nova.  They have other models (Atom, Star) depending on your needs.

Eversolo A8. Love all the features. I really like the ARC in which greatly improves youtube video performances. Sounds great as a preamp.  Replaced my  tube pre. Ripped all my cds to the internal SSD. Couldn't be happier.
