In fact, I personally never heavily used UPnP/DLNA because of the interoperability problem but also because it is totally unusable as soon as you have any large library, the control point discovery phase takes forever. I know some are happy with various CP like BubbleUPnP. I can't say that I've used it much, so I'm not talking out of experience, but everytime I tried, I gave up quickly compared to what LMS + iPeng gave me in term of UE. To some extend, and at the risk of creating some angst, the strength of LMS (having a central server) is also a weakness, especially relying on a home computer (assuming not using mysqueezebox.com) is the complicated and unreliable part for non-technical users. I'm sitting here at the home of friends that have a LMS system but don't use it because of this complexity. They moved to Sonos just because the installation and management is much easier for a non technical person. I've tried to revive LMS by installing it on a cubieboard2 so that they don't have to rely on a big, always-on, crashy computer. Having said that, the openess of LMS makes it a much more powerful solution than Sonos (I can testify that on my own plugin development and current pain with Sonos)

UPnP has this tri-component complexity that makes difficult to have many CP, I think. LMS and UPnP expect the client to integrate the codec which make thing complicated sometimes, especially if you want a large ecosystem of vendors (but that's not the case for LMS). I also think that the client side of UPnP is too complicated, leaving too much room to the player and I'm not sure OpenHome solves this. I did not see if OpenHome was adding synchronization which is a big thing in my opinion It would probably take a large post to list differences and I'm sure other people have smarter comments than mine on these topics. > > I like too the LMS ecosystem but even if i'm not a true "Audiophile" i > care about sound quality and above all user experience as a "melomane". > In this aspect Roon seems interesting for a classical music lover who > like to "discover" new musics. > Something I know from my professional life is that it is *extremely* difficult to design a SW client/protocol and expect it to be adopted by various HW vendors. However good is your solution, vendors like to either do their own (customer lock-in) or 'improve/re-implement' yours and here you go ... To have adoption of SW clients in embedded world, you need to have the scale so that HW vendors see the non-adoption of your SW client as a threat for them to loose share. And to create scale you need adoption - chicken and egg, quite often. Thank's and Regards. Volpone PS: Sorry for my english i live in Paris. LMS 7.7.2 - 5 radio, 3 Boom, 4 Duet, 1 Touch, 1 SB2.
