Coda 11, Schiit Tyr, JC5 or ???

Poured over the forums but seeking repl. for Rogue Medusa.  Sold my Parasound 5ch beast and had regrets at the sale-demo.  Miss the gutteral full bass.  I'm done with ClassD. It's got detail but lacking fullness Want more musicality and like a good soundstage and prefer ClassA/AB.   Tried tube rolling.  Max budget $4k new or used considering Coda 11, JC5, Kinki M7, or new Schiit Tyr pair. All in budget used.  Recent Tyr favorable review in Absolute Sound. Need power for pairing with 4-Ohm CSS towers with Audible Illusions L3A pre.   

Appreciate opinions?
