You can use a source selector and some Y adapter/cable to build your own Tape monitor/loop.
On the source ( CD and phono stage ) output connect a pair of Y adapter/cable, one end go to Freya+ input, another end go to source selector input, the source selector output connect to reel to reel input and the reel to reel output connect to one of the Freya+ input.
Since the $49 Schiit Sys has two input, it is a good contender for the job as a Tape monitor/loop selector!
