In this day and age, it is prudent for a high-end audio manufacturer to continue improving their users' experience as long as it in no way degrades the quality of the listening experience.
This is especially true if a company wishes to broaden the demographics of its customer base by bringing in younger customers who expect a user interface of at least equivalent quality to that of their other non-audio devices.
In the automotive industry's early years, manual transmissions met customer needs and the technology still works today. But customers embraced and now demand automatic transmissions which greatly improved the driving (i.e., user) experience especially for young/new drivers. Similarly, by limiting user experience improvements, high-end audio manufacturers will be left fighting for market share in a contracting audio market.
In my opinion, as a business and non-tech guy, Bryston has a workable utilitarian user interface which is especially frustrating on small handheld devices. Compared with each of the dozens of the other user interfaces on my desktops, laptops, tablets and phones, Bryston's user interface is singularly awkward and archaic in looks, feel and functionality.
I have taken the time to express these views in the hope that I can encourage a change for the good of Bryston's digital products and for me as a customer/supporter of this fine respected company.
My 2 cents.
