Do Integrateds sound better than Receivers?


I have a Rotel reciever as amplification for my system, but would like to upgrade to an integrated amp. One reason for this is that I don't listen to my radio. But the other reason is that I've been lead to believe that an integrated amp will sound better than a receiver. Is this necessarily so? How might having a tuner in the same chassis affect the sound quality of the amp? For example, would a Rotel integrated amp sound better than a Rotel receiver?

Good advice wolf_garcia,

always buy used/demo on everything. Get out to your local dealer/retailer and listen, listen, listen prior to any purchase. Happy Listening!
It's been my experience that similar priced products within a brand (similar priced integrated vs receiver) will sound about the same. A new $500 Yamaha Receiver and a new $500 Yamaha integrated, even with different s/n ratios, etc, probably will not make one think one is superior sounding. If companies save $50 by not adding a tuner or processor, I would not expect $50 in better components in the integrated. If one does a major price increase step in one or the other, then you may start to hear a difference. Again, just my experience from many years. I am assuming 2 similar aged components (same era) from same brand. Comparing two brands does not work since each one has a general "house sound".  If you prefer the house sound of Marantz, then you may like a $500 marantz receiver over a $2000 Yamaha integrated. 
When I was young I did save, save, save and go to retailers to listen, listen, listen. There wasn't as much of a used market because there was no internet. I don't remember ever seeing any desirable equipment in the newspaper classifieds. When I could, I bought some demo units. Reached a point where I was satisfied and then the kids took over my attention.

Things are much more fun now. You can get reliable opinions on a lot of quality used gear and get some real value. Unfortunately, I can't listen to much at retailers anymore. There seems to be nothing between the big box stores and ultra high-end in my area. Three of the high end audio dealers are great places run by great people who will help you put together a nice system at a reasonable cost. It's just that they don't have any tower speakers or pre-amps below $2,000 each on the floor. They'll be happy to order it for you; but you don't get to compare. So I guess, as Joni Mitchell said, something's lost but something's gained.

Either way, I;m much more obsessed now then I was 30 years ago!
