I bought it from Yamaha’s authorized dealers . I don’t recommend u to buy from online. Local dealers having some price difference , like it will little less than from authorized dealers. But for me they have given and excellent demo. Which I didn’t get from reliance and some other stores .And they are recommending the cables also which can produce the good sound ,but its little expensive .Yamaha itself providing all the cables like speaker cables and subwoofer cable and all. We have an option for choose another one also.
