Have you heard or Auditioned the vivid spirit 2 loudspeaker? IMHO it is one of the best loudspeakers available today at almost any price. The vivid range is quite large and will address most of the high-end loudspeaker price points. Happy hunting!
You would need to hook up your UMT+ to the Analog DAC with the I2s cable for the optimum link. Then the UMT would link to a NAS/computer with a ethernet cable. You could control the app for playback via an ipad.It is a good combination.
