What kind of "timing" are you talking about because sound travels a shorter distance from driver to ear than with speakers.
Speed is achived many ways. The crazy part is at times you don't even know it can be improved till you improve it. It is in essence how your amp and headphones or speakers respond to musical changes. The lag I experienced was from power-cords. I also was able to get a faster response from my system with different interconnects.
It seems certain amps are more power cord dependent than others. Also some amps are more interconnect dependent and will show a change. The sound response from the system at first will be better with slower changing music and certain headphones. Jazz and Classical are both slower genres in general. Rock and Metal both need faster headphones and amps. Damping factor is the transducers (driver response) ability in relation to the amps signal. More signal power more damping also this is affected by the headphones themselves. Speed can be affected by the drivers ability to change direction or stop.
It is the amps and headphones ability to alter PRaT. PRaT is a real quality that can be noticed.
Sound time changes are also a real problem coming from different drivers in a speaker system. Headphones have all sound being released in a single per side enclosed enviorment so very little or no timing issues. If you study why single drivers are more coherent and why they reduce the arrival of some of the sound waves out of phase. With heaphones we never worry about the spatial or directional effects from the listening room.
These are some of the same reasons full range single drivers work so well. You have no need for DSPs or crossovers and no physical phase distortion. Though they do have some weakness at both the extreme high and low ends. They do great mids.
When I said the sound travels a shorter distance, I'm explaining that it has no room phase affects on it, or no reflections other than in the small driver housing. There is only resonance.
Look-up Constant Beamwidth Transducers and Single Full Range Drivers. I really can't make this stuff up?
In speakers room reflections are one way that sounds will be disintegrated in timing. Its just a form of distortion that we don't have to worry about as much with headphones.
I can not understand or explain why diferent powercables make amps sound different but they do. It is always from the wall to the amp. Even though the electricity travels from the power pole to the house wiring it is the wall to the amp that changes the sound. Woo amps are super power-cord reactionary. Some amps are not. All my power-cords are constructed with sheets of pure gold. I'm guessing there could be other ways to achive speed but this is how I do it in my system.
Less to do is the speakers clarity of sound from only vibrating in the pure harmonics of a single guitar or drum. Thus the color is only distortion added harmonics in the tone. A single guitar is also much more easy to record than an entire live band. Less microphones (except with drums) a sonic purity of purpose so to speak. If someone can convince me that a whole band is easer to reproduce than a single instument I would love to hear why.
A single instument can be much easer to blend into a mix, as there is no mix only correct volume levels.
Take an acoustic guitar and hold it up to a door. The guitar body, with the strings is now the creator of the sound energy being distributed by the door or even table top. The wood slab is the speaker. Now hit the door or table top with drum sticks while the guitar is playing. The guitar in this situation will lose both the listeners mental focus and now we also have the addition of another vibration.
Anorher reason for a single guitar track or single singer to demo gear is the feeling of being closer. Everyone wants to be a little closer to the sound.Edited by Redcarmoose - 9/5/14 at 12:08pm
