Good value upgrade from PSB STRATUS GOLDS to ?

The upgrade bug is beginning to Bite. Can anyone suggest a good value replacement for the stratus golds. I listen to mostly to smooth jazz and classic rock. My listening room is fairly large at 27 by 18 feet with a vaulted ceiling. I would hope to retain my existing components. Bryston 4bst, Rogue 66 Magnum preamp, Msb dac with p1000 PS, etc. Would appreciate anyones thoughts.

Thanks,
Alan
