I am shopping for a relatively low priced receiver to replace my old Pioneer 5700S. Have narrowed it down to either the Yamaha 5630, Yamaha 5640 or the Onkyo SR501. Can anyone make a recommendation or have any experience with any of these three models? I have Bose201 Series 5 for my mainn fronts. I would use it for both listening to CD's and watching movies. Any info is appreciated. Thanks
