No. I had it directly connected to the amp at one point. Lately, I have the BDP-105D, HA-1, Sonica DAC, and UDP-205 connected to a Kramer 4-way XLR switch that goes through the XMC-1 XLR inputs. With this configuration, I can use J River Zones to simultaneously stream to the SDAC, 105, and 205 and select the input with no level matching required.
I picked up another Kramer so I can try the SDAC direct again without rewiring the world.
If you have J River, you can do setup linked zones for the HA-1 and SDAC and change inputs to compare them.
