Well in comparisson my mate bought a BOSE sysem a few months back. It cost close to 3k euro. We compared a DVD one night and noticed that the BOSE had too much volume coming from the center speaker and that the sub lacked the same punch at times. Even thought i didnt say it to him I prefer my panasonic for sound as it the spread of sound is even across the front 3 speakers. the SUB is excellent and I dont notice it drown dialog or distorting. but then on a good movie the sitting room door it rattleing away! lol

Not to mention mines cost 5 times less 6 years ago. Also on Max volume I get little to none distortion, I just have to turn it down because it is get sore on the ears! lol
If I was going to buy a denon/onkyo AVR I would need to use my current speaker and save up a bit for a new decent speaker package.
My only concern is would I have the possibility of damage to either the AVR or the speakers as they may not be matched to each other.
SimonsPlasma , that is the correct number on the subwoofer but it is not a stand alone subwoofer. the only input to the system is via the dvd player. there is a control cable from the dvd player to the sub, where the amp is built in for the surround speakers and the sub itself. can I use the panasonic for just the sub? ie, remove the surround speakers, and run a cable from the preout on the AVR to the panasonic system?
