What is meant by a "fast" pre amp

............Are you serious?? The guy asked for audio help, not english lessons.

Sorry, I thought someone else made that comment.

I am pretty ignorant regarding the technical aspects of an amp, but, surely if it sounded faster, that is, if the sounds don't take long for the attack and the decay then a CD with a song length read-out of, say, five minutes exactly would play shorter than five minutes. OK, so this obviously isn't the case, so I am assuming it refers to the length of time for the amp to take the sound/s to a particular sound volume level......does this make sense????......Wait a minute, that doesn't make sense neither - the song would still finish earlier!
I am guessing it has more to do with what Phd refers to as "sounding" faster than actually "being" faster.......the more I think about it the more confused I get. Of course the whole speed thing is totally determined by the RPM of the record or CD. Could "faster" simply be semantic quibbling that could just as easily be referred to as "crisper"?
Sorry if I have confused you even more Brf.

That was a hell of an answer. You are always one to dig deep when it comes to figuring this stuff out - good to know you are around.

Yes, I got that - I was just referring to the "sounding" bit.

As for me, I am just a listener and am happy to let brainy people like Almarg (who obviously loves the technical challenges) do the dirty work for me.

Your quip about heavy amps got me thinking about something - I have a couple of CD players, both highly rated - a Bryston BCD 1 and a Naim CDX2. One weighs about four times the weight of the other (rough guess). The Naim feels like a block of lead - I wonder why. They both sound just as good, the only difference I have found is the shipping cost to get them to me.
