I saw a couple of amplifiers for sale in the classified section which were priced over 3 lakhs. Will there be a difference in sound from a 30k -50k amplifier? Of course, there may be improvement in the sound (may not be too, if the synergy with the speaker is not right, but that is a different story).If at all there is improvement, is it worth the extra money, that is almost ten times the price. Definitely NO. At least no much difference that a human ear can identify. Any body have a difference of opinion. I think people who use such expensive amplifiers are fooling their mind, making it believe that the sound is 10 times better because you paid 10 times more money.
