I have a Denon AVR-3300 and Mission 750LE fronts with a 73C centre. I have been thinking of adding an offboard 5-channel power amp, probably the Rotel RMB-1075. My question is whether upgrading the speakers (eg to Dynaudio Audience 52/42C or Ruark Epilogue/Dialogue) would bring greater improvements. I want to do both eventually; any opinions on which should be done first? One alternative is to totally replace the Denon with a pre/pro combination and tackle the speakers after that. I'm a bit lost. Thanks for any feedback.
