Absolutely recommend the Rivo or Rivo+. Note that I actually purchased the Rivo, The Rivo+ is an upgrade and has better and more inputs and outputs. I bought the Rivo because I considered the USB out to be sufficient to flow into my Peachtree Carina 150 DAC, which is a high end 9065 DAC.
My full review (recommendation) of the unit can be found here.
