Amp "timing" ?

Comparing two power amplifiers I owned many years ago.: A Dynaco 410, and a GAS Ampzilla. Through any loudspeaker I owned at the time ( Klipsch Lascala; Dahlquist DQ10; Martin Logan CLS; AR3, and a pair of JBL monitors, ) the Dynaco was slow and ill defined compared to the Ampzilla. Although some tube amps sounded good on the Klipsch, they did not have prat. All the amps were " as new " from the manufacturers and had been "broken in ". I still feel tube amps have a problem in this area ( lets keep the attacks down please ). I have owned some beefy ss power amps that have " grip ", so to my ears, this is ime. If a system shows signs of anemic bass quality ( slow and ill defined ), I will move on. Sorry if I made anyone ( wolf ) cry. Enjoy ! MrD.

I have read about ’speed’ and ’timing’ in regard to components and could not get my head around what that meant. Probably neither are very good terms.

"I have heard it myself when trying various tubes."

I’m a new audiophile with limited experience. But just last night I changed tubes in my AR LS-16 preamp with some tubes rodman99999 sent me to try out. My immediate impression was that everything sounded more laid back and the music did sound ’slower’ which I knew was not possible. It was really a shocking impression and I still don’t know how to describe it. Maybe it has to do with stridency. I don’t know.

The point being, I now have a understanding of what some folks might be trying to say and just don’t have good enough words to say it.

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).
