I just bought Klipsch HD-500 speakers and now I am looking for a receiver.  Ive narrowed my choices to the Onkyo TX-SR607 and Onkyo TX-SR707.  The 707 model is the next level up but also a few hundred dollars more.  I have a medium size living room with a 50 in Plasma, Blue Ray and my 5.1 Klipsch speakers.  My questions are, is there a big difference between the 607 and 707 receiver?  If so, what are the main differences and is it worth a few hundred dollars?  Any additional info would be very helpful and much appreciated.  Thanks!
