Here is an update,
As I mentioned earlier, I got an offer on polk audio tsx330t from one of the forum member"AmitKG". Last Sunday , I went to his home for auditioned. Spending hours on listening various music on his amp(Yamaha 500 amp , onkyo receiver), I decided to go for the speakers. I bought it @15k.
Wanted to close the thread now.
And Many many thanks to the members who stepped into this matter and try to help me out of this situation.
