This past monday I got my Odyssey Khartago Mono's With cap upgrade!

without going into detail, Lets just say that the difference between them and the NAD C370 I have is astounding. The NAD isint a slouch, Its one of the most highly rated amps in its class, but these Odyssey's are in an entirely different league. Highly Reccomended! I realize that they are more expensive than most of the people on this board would be willing to spend on amplification for a 2 channel system, or even a reciever but the speakers definetly respond to being driven by better amps. Dont limit yourself into thinking it wont make a difference because the speakers are only X amount of money.
