This horse is so dead. It reminds me of the Skittles commercial when the Zombie on the bus says "You're boring me to death. I'm already dead and you're boring me back to death!"

No one is going to convince anybody else they can or can't hear a difference between amps.

If you can hear a difference, spend extra money on your amps.

If you don't hear a difference, buy a reliable amp that has adequate Power for your application and is reasonably priced.

Just for fun somebody start a thread on the audible differences between cables :-)
