Not merely....LOL!!! I have learned that multi-channel avr's offer more bang for the buck when compared to both stereo receivers and/or 2 CH integrated amps. Especially, when compared to 2 CH integrated tube amps. That is why I was mentioning SS amps. Not necessarily 2-CH amps in particular.
When you directly compare what a HT avr offers albeit inputs/outputs and power vs what a stereo receivers offers, then it is easy to see that HT avr's offer more bang for your buck. My Denon X3300 sounded just as good, if not better, than my Cambridge SR20 in stereo. Furthermore, the SR20 did not offer much bass management. In fact, the sub out (LP) was fixed at 200 Hz if I remember correctly. The left and right mains continued to play full-range. Having bookshelves as my mains created a bit of a problem. Good thing, I never really cranked mine up very loud.
Cheers,
