To be honest, when I first started out I fell for the hype when it comes to amps, power ratings and the like. Add speaker myths about efficiency and the dos and don'ts in all things audio. It was a learning curve for me.
Right now I'm running a 70 watt integrated with 87db rated speakers and experiencing the best sound ever. It's the perfect match for my apartment living room. Everything before it was simply overkill.
All the best,
