I have spent 4 years to search for my HT(sound) and increased my budget from 50000 to 1 lakh in the process. This forum helped me a lot.
For the TV, it took me just 6 months and 46,000.
Well, that speaks for itself.
Of course the quality of the sound is the most important aspect of a music system. How loud you can blow it is another issue. I don't think that reason behind buying a home theater system is to play it loud. It is to enrich your surroundings with the audio you are playing which could be quite enjoyable if you are not trying to break the glasses with volume.
