I started investigating digital in 2007 with the introduction of the first Linn Klimax DS. I finally abandoned my Naim CD555 player in 2011 with the release of the second incarnation of the Klimax DS/1.
Linn originally championed open source software and refused for many years to enter the software development business for a control app. Kazoo came about because all of the open source third party developers eventually realized that no money was to be made working on an app solution for the DS.
Since then I, and many others, have suffered and complained about Kazoo for more than a decade. My Naim friends have endured similar heartache with Naim’s own proprietary control point software.
Linn users were finally granted a reprieve when, after 3 years of vocal complaining on the (now defunct) Linn forum, we were granted access to a modified implementation of ROON. Our Linn players are now Roon “capable” but not Roon certified.
The point I am trying to make is that perhaps these companies, Linn, Naim and dCS, belong hiring true app developers instead of trying to do things in house. Somehow other companies, particularly the Asian manufacturers, have been able to put forth apps which perform better than the 3 large UK audio companies.
The previous poster on this thread mentioned Aurender and his satisfaction with their control point solution. I remember when Lumin released their first software app. It was actually an extremely interesting development as a new member on the Linn forum introduced himself as a new DS user and a computer programmer by hobby. He picked our brains and used us as beta guinea pigs to develop the very impressive Lumin software control point. You can imagine our surprise when we discovered the subterfuge which was that of him actually being a Lumin employee who was sent to the Linn forum to “integrate” with us and do market research and software testing for their yet to be released Lumin player - which at the time was a blatant copy of the Linn KDS.
I guess the moral of the story, imho, is that developing control point apps and software is not easy and the task is best left to the experts who do it for a living - instead of trying to develop internally.
Just my own opinion. For now I continue to use ROON and thank dCS for making all of their units fully ROON certified (unlike my Linn product and its “faux” Roon certification).
