I hate to say this, but with those speakers I highly doubt that you will notice any difference by going with the Krell or McIntosh. Don't get me wrong, those are ok speakers, but nothing more than ok, and for the money you could do better. If watching movies is your primary goal, then I would recommend looking into Seaton Sound or Danley Sound Labs as they have speakers that will stomp the crap out of those Klipsch speakers for movies. As a matter of fact, Klipsch even makes some speakers that are leaps and bounds better than the RF-7ii. For example, the Jubilee, or La Scala. You could get a brand new pair of Jubilee and use a La Scala for the center channel and still come out less than upgrading to Krell or McIntish. That would give you one of the best theaters on this board, and make a whole hell of a lot more difference than just swapping your components. You would be a complete fool to buy those new components over buying the Jubilee's, La Scalas, Danley, or Seaton speakers. The RF-7ii's lack cla9rty, and their mid-range sounds dull, plus they are very colored. With that being said, you could upgrade the electronics all day long and you will never be able to improve it over what something like a Denon AVR4311 or Integra 80.3 could do. Go with some of the speakers that I listed above, and I can promise you that if you do that, you will thank me later!
