Thanks for all your advice guys. I don't want to spend more than 1200 on a reciever, so i am really leaning towards the H/K AVR 645, it looks great and is second to best in Harmans lineup of recievers, although, it does state only 75 watts per chanel, is that enough? My friend told me Harman/Kardon recievers are really efficient and is actually more than enough for the system I am getting.
Thanks!
Miguel
