thank you guys for the inputs. There got to be a reason that seperates cost much more than receivers. I tend to make a compromise to go for integrated amps.

It looks like NAD C352 integrated amp could be a good choice for me. But the user review for this product on audioreview.com is not that good, the overall rating is only 3 of 5. I am wondering if I should go for HK3480 that has a lot positive review (someone even think it is comparable to a $1000 integrated) or go to ebay to find a integrated Rotel such as RA1070 for a half price.
