I currently have the Pioneer VSX-C301 receiver, which works just fine and is slim enough to fit under my Tosh PF2. However, I'd like to use the DVD-A/SACD feature of my Pioneer 565 DVD player. The only logical upgrade, given the fact I want it to fit under the TV, is the Pioneer VSX-C501. The question I have is this; I currently have the Canton Movies 6 CX speaker kit (which sounds just fine). These are rated at 80w max according to the homecinemaheaven site (where I bought them). If I change to the C501, will the fact that this receiver has a higher output affect/damage my speakers? The C301 is rated at 75w x 5 The C501 is rated at 100w x 6 The power specs quoted for amps/receivers are misleading to say the least. Should I upgrade my speakers also?
