Hi Balaji,
..... Since you are in Chennai, you can audition it at my home if you want. I cannot comment Norge products because I haven't auditioned it. But Norge products are slightly costlier than Craftel.
In my opinion, audition the product and buy whether it is Norge or Craftel. I think our forum member Mr. N. Murali (Chennai) has Norge 2060 amplifer. If you can audition both Norge and Craftel, you can come to an idea.
All the best.
