There is also a psychological effect to consider. I have noticed that when you upgrade a cartridge and get significantly more information, the music can "appear" to take longer to play, but actually doesn't. There could be a parallel here where there is significantly more information provided from an analogue front end.
Frequency response variations can also give significantly different impressions on the musical flow. I have heard different resissues/mixes of the same performance alter apparent timing to such a degree that I've had to recheck it was the same recording and performance.
