What does 'Fast mean?

fast means no smearing of the sound.

Oh, other classes of well designed amps can`t track the input signal as acurately or quickly? NONSENSE.

Again, my 1970's hand held, transistor radio sounded fast. Why? Because it produced threadbare sounding music without body, soul and foundation. It played a 3 minute song in 3 minutes just like a Lamm SET amp - no faster.

A Mcintosh 402 amp won't sound fast, but rather it will sound beautiful and full. A Toshiba 3950 DVD player (I own one and like it for the money - $49 after rebate) sounds very fast due to its lack of body and weight. Perhaps I am to simple here, but it sure seems that way to my ears.

Michael Johnson in the 200. THAT's fast!

Boa2, that does sound fast. You got anything faster? In regards to this hobby I do, how about a vacuum cleaner set to maximum suction hooked up to your wallet. Now that is fast! If you hear a sucking sound, you know where I've been. If anybody finds a wallet with my initials, please at least return the credit cards & drivers license, you keep the wallet & what little money if any, remains.
