The time has come and I request advice...

+1 Aurender.

I would not go the Roon route, costs, adds complications, not much of a long term future. Aurender Conductor app is well regarded. It is improving as well. 

My personal judgment on Roon is from personal experience with it (complicated) and forty years of implementing information technology. I have experienced generations of operating systems, hardware, and dozens and dozens of software suites and hundreds of single purpose software products. Software like Roon has a very limited life as streaming becomes. Main stream and major vendors produce their own better and better products and the revenues dry up for Roon and they get purchased and disappear into the history of software. There is a question of how long it will take… but the time will not be measured in decades but likely a few years.

Most likely the functionality of streamers continue to improve, leading to reduced subscriber numbers until they get bought and incorporated into one company’s products. Or they try and hold on, updates become less frequent and customer support goes away, and they slowly disappear into obscurity. Or they shift to licensing direct to manufacturers to incorporate inside components, instead of separately sold to users. 

Today’s special purpose software gets incorporated gets incorporated into the operating system of integrated suite. That has been the way since, well, the first computer language.

If you’re a lifetime user, then just enjoy it until you need to buy something that doesn’t use it. It’s nice not having a monthly fee.
