How would the Yamaha PSR pro (76 key version) sound through a conventional hi-fi system? - I ask this, because I have a 100 watt RMS Stereo HI-FI system at home, and wouldn't be able to afford a complete PA set up for many hundreds of $$$. (Pounds in my case!) If I brought a Yamaha pro,(which I could afford at 2,499...the price in England) and got it home - and it sounded terrible, that I would regret!. My system is loud at 100 watts, but would it be able to handle the bass/Treble frequencies etc. Loud doesn't necessarilly mean good quality does it?

Does anyone else use normal Stereo HI-Fi systems to amplify their keyboards?

Sorry if this kind of question has been asked before.

Thanks in advance.
