Hi all, I currently have an AVR-4800 Denon receiver. It's circa 2001 and is THX certified with 140 watts per channel x 5. I'm wondering: A- Do you have separates? B-Are they providing a better listening experience than a reciever you had? C- How much better? I ask because I'm thinking about upgrading. I was told by a salesman at a local B&M that I'd have to upgrade to much pricier gear to get a significant improvement in sound. He said don't bother with entry level separates at all. So, what do you think? Also, if I added just a separate multi channel amp do you think I'd get much sonic improvement? I often wondered since even adding a 200x5 watt amp would not necessarily increase output by even 3 db. I know power output is only 1 small portion of the game, but still... Oh, BTW, I'm running a Diva Swan speaker set with the 6.1 towers and a big center and dipole surrounds... and they're not particularly efficient.
