Based on my experience I believe JRMC is the audiophile standard most used by serious enthusiasts. Even people who run other applications for specific playback needs frequently use JRMC in addition to the other apps.
The combination of feature set, tablet remote control, and ease of use (compared to other apps) is unmatched. Like all applications there is a learning curve with JRMC if you want to take advantage of its powerful features, but it’s not the steepest. If you like to poke around to figure things out yourself and can use forums to get questions answered, JRMC is a great match for you.
The tablet remote control app JRemote is one of, if not the, best in the business. JRMC supports so much it’s hard to list it all here. For example, almost all relevant file formats, PCM, DSD, multi-channel, UPnP server/renderer/control point, full library management and metadata editing, CD ripping, file conversions, WASAPI (Windows), ASIO, resampling, convolution, parametric equalization, room correction, dynamic range analysis, theater view, and on & on…
