Amp "timing" ?

Negative feedback works great for steady state sine waves, which ain’t music

so let’s think about timing and Miller Carbons example....and be glad car timing does not depend on negative f/b

because I am actually a worshipper in several tents, I own and listen to a NAIM amp in the PRAT camp, along with 6 others....

most however are fairly low negative feedback

have fun

Also, words suck for describing music and anything Audiophile....
so I would think of PRAT in a less narrow fashion....

kinda like reading about... wine..... the howl of a tricked out flat 6, the swing of a sweet light double, the love of a good bird dog, maybe even women...,words

Here's what I hear and I don't necessarily attribute it to the amp (though more about that in a minute): when my system sounds 'right' with a good recording, particularly of something like piano music, I hear the attack (with the fundamental) and the harmonics, which decay. There is an aspect of 'timing' to this that gives shape and body to the presentation of the instrument. That is different than what I understand to be "PRAT" and I'm not sure what to attribute it to beyond the recording. I do know that the amps I use on my main system-- the Lamm ML2 SET-- seem to contribute to this because I hear this aspect more through them than some other amps that have been in the system. I'm not staking out any absolute position on this, other than to observe what I hear as an end result. It could also be part of the rest of the chain-- starting with the phono cartridge- where I've heard more emphasis on leading edge with some cartridges (e.g. Lyra) than others ( Airtight). 

I have a Linn now, but my point was that those specific tables had absolutely the same speed, and the music presented was in identical pitch (which I'm extremely sensitive to, as are most people if they know it or not). Maybe the dealer should have been using a crappier table for comparison than an expensive direct drive Denon. I don't think "prat" is a particularly useful term and am glad it's seemingly fallen out of fashion as I rarely see it anymore, even in UK audio mags.

millercarbon,

Belt or chain?

Neither.
