Hi all. I'm currently running a Yamaha RX-V575, Klipsch KB-15 (Icon) bookshelf speakers, Klipsch KC-25 (Icon) center and a Klipsch SW-350 8" subwoofer. I've had this setup for about a year. The system can get loud but that's all it is, loud. I feel I need more depth/clarity/detail. I'm in the market to upgrade everything. My room is approximately 9300 cubic feet... Behind the listening position (living room) is the dining room with windows. I have vaulted ceilings and everything is open. I've been looking at the Def Tech SM65 for LCR and PSA XV15SE x2 for subwoofers. Due to my layout, surrounds are unfortunately out of the question and that makes me pretty sad. I'm going to be posting this thread in other subforums pertaining to the component I'm asking about. My question for this subforum is- due to my room acoustics, would I greatly benefit from a receiver with Audyssey MultEQ XT32 over my current Yamaha? I'm looking at either the Denon X4100 or Marantz SR7008. Seeing as I only have a front stage and subs, should I go another route? I'd like to keep the receiver around $1500 or less. It will be used primarily for television and movies.
