Hey Zhyn,
Welcome to AR. The difference between an integrated amplifier and a receiver is that a receiver has a radio (or tuner in audiospeak). Usually an integrated will have better quality parts than a receiver of similar cost because of being able to apply more money to less parts. If you want to listen to the radio in your area then there is nothing wrong with buying a good receiver from a company like Yamaha RX797 or a Denon DRA395 or 685. In integrated amps the Cambridge is an excellent choice as are NAD (320BEE or 352) or Rotel. As to speakers the Phase Tech is a solid choice. Since you live in Canada you might also consider the Paradigm Mini Monitor or the PSB Image B25. You might also consider Energy speakers and Axiom (an online dealer with a good reputation). So you can see that you have a lot of choices. Be patient and think about what you really need in your situation. If you can, audition your speakers as well as possible. If you have to order without an audition then make sure you have a trial period and return privileges in case the equipment doesn't satisfy you. Hope this helps a little and best of luck with your new system.
