Dear Raul,
I am surprised that such an experienced audiophile as you seem to not differentiate between incorrect absolute turntable speed and speed instability. First:
**** Now, if what you are saying is that perfect timing is only in live music ****
That is exactly what I’m saying and I don’t understand why that should surprise anyone. A live performance will always have more rhythmic impetus, “groove”, PRAT, whatever one wants to call it compared to a recording of same and will be, by definition, “perfect”. A recording may get very close depending on the quality of the equipment used to record/playback; and some listeners may be more sensitive than others to timing issues. Btw, I don’t agree with your comment:
**** Not only me but any human been is more sensible/sensitive to timing than neutrality, ****
I have known many audiophiles who are much more sensitive to changes in timbre (bright, dark, harsh, smooth, etc.) than to timing issues. As I mentioned, and with respect, you seem to be also.
**** Example: if my TT instead to spin at 33.333 rpm spins at 33.332 rpm: can we detect it?. ****
Probably not. However, I can tell you that I know individuals with “perfect pitch” that can detect very very small changes in absolute pitch in music. Let’s use a more realistic deviation from perfection; say 33.34 vs 33.33. This may be heard as a very slightly faster/energetic performance of the same music; but if it remains STABLE at the “incorrect” speed it is not perceived as particularly problematic. But this is not the issue; this is not what we are talking about. SPEED STABILITY is the issue. The problem is when the turntable’s speed does not remain locked on one speed and is constantly changing as is sometimes the case. Even changes in very small increments are problematic. This causes a very audible reduction in the rhythmic impetus of the music and the expressive value of the performance.
**** Anyway: which are those speed unstability limits? zero tolerance? because the timing problem in audio always existed and if in the future nothing change allways will be there. We can't avoid it. So, which your conclusion about? because even in the LPs where you like its rhythm exist a timing problem ! ! ! ****
I have no idea what those limits are; and frankly I don’t care much. As always, the numbers only tell part of the story and I prefer to let me ears tell me whether A or B sounds more like the real thing. The rest of your statement we can agree on. Again, recorded music will always fall short to some degree of the standard set by the live performance of the same. As you say, “We can’t avoid it”. So what? I have always felt that this was a given and this doesn’t have to mean that recorded performances can’t be enjoyed limitations and all. We try and minimize the problems with good equipment choices and setup and then we make the choice to either listen to and enjoy the music or focus on the equipment and it’s inevitable problems.
