I currently am running a pair of LSi15s, 9s, and an LSiC off of my HK AVR 300. The receiver does an all right job, but there is lots of room for improvement. I am considering upgrading the receiver, but am not sure which route I should take. I could either use the AVR 300 as a pre amp and buy a Parasound or Rotel 200 x 5, or get a higher end AV receiver such as a Denon 4802 or HK 8000. I have heard seperates are the way to go, but am not sure which route I should take. Any suggestions would be great.
