Go for Yamaha RX-V673, its not only the "Dialog Lift" or "Vdo upscaling", its the circuitary or amplification stages that are improved in 673. Approx. 36000/- for 673 is not bad But you may have to compromise on warranty. As fa as prices in india are concerned they are not going to be as down as this ..ever! Try buying older 671..not one will let you for less than 32K.
