New to 5.1 what AV receiver

[TK421]

Hi People, I have just got mordaunt short avant 903, 904, 905 for next to nothing so I am going to ditch the cheap soundbar. My question is that on the back of the speakers they state "max amplifier rating 100 watts RMS", so if I purchased a AV receiver with 130w per channel is this going to blow the speakers? As I am new to this can someone advise? And also has anyone got any recommendations for an AV receiver to suit these speakers with bluetooth in mind?

First, it's very unlikely that the receiver you're looking at is truly 130W/ch for all its channels. There's a lot of marketing B.S. in AV receiver specs, so unless you're buying an older powerhouse AV receiver in the used market then the chances are that the real-world power per channel is a lot less. Have a read of this thread LINK, particularly posts #5 and #16 where some of the myths are debunked.

Second, even if you did have those sort of power levels to play with, all amps and AV receivers have a volume knob. That means you dial in volume to an appropriate level rather than whacking the knob round to max power.

It's actually pretty difficult to kill speakers with too much power unless you do something really stupid such as giving the speakers full power from cold switch on. You're more likely to do the speakers some harm with an under-powered amp running flat out. That's because of distorting. When an amp is straining it creates a lot of distortion, and distorting causes the voice coils to overheat and short out.

Thanks for clearing that up, I will take a look at the thread you mentioned.
