We started with Squeezebox almost 15 years ago and went from there to Sonos (and regretted that profoundly) and went back and then via AssetUPnP onto Roon. The past 6 months we have been using MinimServer with BubbleUPnP (for Open Home).
LMS/SB was a perfect match for us, with a Transporter as the centrepiece. Unfortunately, the control points slowly deteriorated, accounting for our diversion into Sonos. We kept the Transport for dedicated listening until we finally had to throw in the towel. Then when we bought the Naims, we purchased AssetUPnP to replace LMS. However, having not just Naim renderers, we needed something which would allow us to play multiroom and thus purchased Roon.
Roon is very, very smooth and handles diverse renderers very well. However, since we only use the streaming part and none of the augmented metadata features, we have chosen to phase it out in favour of Open Home. The accumulated price is simply too high for that one feature, however brilliantly it may work.
Even if it is cumbersome to configure, the MinimServer is very flexible when it comes to metadata structure, which allows us to have radio stations inline with albums and podcasts, and present it on the control point in an intuitive manner. VTuner and TuneIn are fine for browsing new radio stations but much too tedious for daily listening. On top of this, we put BubbleUPnP to support shared playlists and multiple control points.
We have an Open Home control point in the making right now and have started looking into the possibilities of supporting multiroom. Until that is done, we use mainly the Lumin control point on mobile and tablet. I have yet to see a good control point for desktop use. Kazoo works but isn’t brilliant.
