Pre purchase: configuration support

[RJHD3]

Trying to work through whether or not a Devialet could support my current set of source component and output needs.  And which model is best equipped to do so.  My needs:

• Tape loop (pre-out and pre-in) for a reel to reel
  
• Phono in (have a phono pre already so need not be a phono board setup)
  
• Sub-in
  
• USB in for a Roon Nucleus+ (or Ethernet, whichever is more likely to be supported further along
  

So far I think that’s a need for a line out, two configurable line in, and a sub line out.  I don’t seem to be able to find an example of a unit with 8 RCA jacks that could be so configured.  

Admittedly new, but searches for tape loop yield no results so I thought I’d just ask the best and brightest.  Thanks in advance for any help in confirming which model might best support this. 

PS: power is not a consideration, it’s going to drive a pair of Zu Druid V speakers and a Submission sub. I’m not worried on that end.
