Prices do vary a lot on Amazon. When I was interested prices would vary from 28.5k to 33.5k.Price of 2502 is always exaggerated on Amazon.
Mintoo Electronics in Bhagirath Palace, Delhi is authorized dealer of Crown and JBL amps. They retail it for 28300/-. Anyone looking for one can give them a call.
Twice I bought from Amazon seller VMT for 28.5K and both amps were defective. Other seller were selling same amp for about 33.5 that time.
When I saw its price 29.5 listed by Paras Pro I had to buy it.
May be VMT is selling repaired pieces or he is a high volume seller.
