It is not uncommon for keyboard players to start with home Hi-Fi system for their keyboard amplification needs although over time most keyboard players will use keyboard amps, near field monitors or PA systems. The main reason is that the dynamic range of keyboard sounds easily exceeds the dynamic range of home Hi-Fi systems and if the volume of Hi-Fi system is set high your keyboard may blow out your Hi-Fi amp or speakers. Usually the output signal levels of pro keyboards are much hotter than home Hi-Fi equipment, so if you pay attention to your Hi-Fi system volume setting so as not to overload it, you should still be able to enjoy your 9000 Pro at home with your existing Hi-Fi equipment. Keyboard amps or PA systems sound different though since they are designed to work with instrument amplification, they are much louder, clearer, and able to handle much wider dynamic range of music (but not as delicate sounding as home Hi-Fi usually). Since recorded materials like CDs, DVDs have been processed (compressed/limited) to fit into the dynamic range that home Hi-Fi system can handle, they usually sound great. If you do not have compressor/limiter, you will have to take extra care not to overload your Hi-Fi equipment. Otherwise, there is no reason why you cannot enjoy your own music through your Hi-Fi system for now. When you save enough money to buy proper instrument amplification, I recommend you get separate keyboard amps/PA system setup for proper match of equipment in long run.

When I play, or practice at home with my wife, I use a little Aiwa compact system. It has 60W X 2. For us it is plenty of amplification and sounds pretty good, especially at lower volume. We also sing through it, but I also have to agree, that you have to be careful not to blow out your amp. or speakers. I turn it up a little more than half. Loud enough for us and save for the system. Have fun, Eric

Jupiter,
Assuming you have a pair of efficient speakers, you have more than enough loudness for 100 W RMS.
The volume of sound/music produced by a sound system does not depend on raw wattage, it also depends on the sensitivity of the speakers. If the sensitivity of a pair of speakers is at, say, 91dB/1W 1m. With 100 WRMS, its maximum loudness should be around 112dB (with twice the wattage, there is 3dB increase in loudness). However, if your pair of speakers' sensitivity is 85dB/1W 1m (most European made sweet sounding speakers are usually less efficient but more pleasing sounding), with 100 WRMS the maximum loudness is about 106dB, only one fourth the sound of the first pair of speakers. Most people are very comfortable using 1 to 2 Watts of power when listening to light music (around 90dB). I consider 100dB to be more than I can tolerate for music listening anyway. So you should not have problems with your 100 WRMS Hi-Fi setup at home for keyboard amplification if you set the volume knob to no more than 12 o'clock position to avoid accidental overloading.
