I think it is a mistake to think that there has to be a compromise between convenience and sound quality. Personally, I demand both.
I use Bubble uPnP with my Devialet Reactor, as it is not Roon Ready and I have an Android phone. If I had an iPhone I could use Roon and Airplay. Bubble uPnP is just as quick as using Roon, but Roon is much more feature rich.
I can use my Devialet Expert Pro with HD sources in various ways: (1) via Roon Ready, wired ethernet from Innuos; (2) via uPnP, using the Bubble app; (3) via usb, which is excellent out of the Innuos; and (4) from a laptop using the Devialet Air wireless protocol. They include Roon and non-Roon options. I have used them all and blind tested I doubt anyone could tell the difference. I certainly can’t tell the difference. There does seem to be an improvement on the Auralic Aries. My kids and wife use the same system with Spotify, which is built in.
The convenience, besides Roon’s feature set, is that the unit will detect any of these sources being sent to it and play. Even if the unit is in standby, it will wake up and play, with a delay of about 10 seconds.
Many systems now operate like this, or similarly, and some work with Alexa. It is convenience without compromise.
I happen to greatly enjoy using Roon and would not consider a product without it. I am certainly not alone, others have said the same on this forum. There is no need to compromise on that, because there are plenty or Roon Ready streamer/DAC products that are as good or better than PSA DACs. The reality is, as I read recently in a HiFi News review of a new $21,000 unit, that most streaming DACs have narrowed to a level that they mostly perform to a very high level and you can hardly tell one from another.
With regard to mp3, it is the perfect balance of required bandwidth, mobile storage capacity and sound quality. Teenagers and 20somethings have huge numbers of tracks in their Spotify offline storage for listening on carbs or wireless headphones. 16/44 or higher defeats this practicality.
