You need to expand budget to 25k & you can get Onkyo 3200.
For, 20K, NO THINKING. Philips 3571 period. I goes for 15.5K.
Go for Philips 3571
Real Value for Money .... @ 15K
Sound Quality can give Onkyo a run for it's money
Needless to mention it's a DVD player also
2 Aux inputs + 1 CoAx + 1 Optical + 1 mp3 link (ipod) will serve every purpose....
