I do have a year at the minimum before I'll look at a source upgrade. In any case I'll definitely try to listen before I buy. I've have a very good run with blind buys: Except for the Trishnas and the Gaanam, everything I've bought so far was bought blind, based on just research. I don't want to push my luck as the price tags start getting bigger! 
No problem, Ranjeet! Everything is on topic
