Not sure whether to post here or in Speakers area but here goes... Denon AV-A10SE & POA-T10 Kef Q55.1 (Bi-Amped) Fronts, Q95C, Q15.1 Rears Crappy Yamaha YST-SW120 sub (being replaced by REL Q201e) Arcam FMJ27 DVD is staying! I've already got top quality cables/interconnects I've got to stick with 5.1 for now due to room logistics. For best sound improvements which do think I should upgrade first? Speakers or Processor/Amps? Any thoughts? Mark.
