I enjoy RS6 with IEM's but have an XDuoo XD05 Bal2 incoming to use with over ear headphones, especially harder to drive planars. My question is how best to connect the RS6 as a digital transport to XD05 Bal2, whose rear panel connections are shown below. Would I use the RS6's L.O. or Bal. L.O., and into which input of the XD05 Bal2?
Alternatively, is it possible / best to connect USB out from RS6 to USB in on the XD05 Bal2 if the RS6 will see the XD05 Bal2 as an outboard DAC and just feed it the signal?
Clearly I need guidance from those more knowledgeable than I.
Thanks for any advice / recommendations!
