no, that's wrong. what you are referring to is jitter, as Chris explained. 
Jitter in audio is really bad. The Repeater doesn't have that problem, at 
least so far as I can hear.

Jitter in control data is also bad, because you cannot adapt to the random 
variation. (meaning, if you sent midi commands to a synth, and the time 
the sound to come out had some variation.)  From what I understand 1ms in 
jitter is detectable and annoying for trained musicians.

On the other hand, latency is more forgiving. If the latency between "do 
this" and the sound coming out is less than 10 ms, most people will be ok. 
For me it seems that is not good enough, as I can detect that latency. 
Probably that is the result of spending too many hours as a teenager 
practicing picking technique on guitar, when I should have been trying to 
meet girls.

With greater latencies, people will be aware of it, but they can adapt if 
the latency is constant.

Yes, and for me it is easy to hear the latency as the speakers are farther 

Your ears can locate sounds and your brain interprets the distance from 
location cues. You can adapt your playing to that if you are experienced 
with it. What I suspect happens for me is my ears have located the sound 
a particular distance, yet there is an added delay throwing that off. I 
find it annoying. It is the same reason I don't like playing midi guitars.

If it doesn't bother you, by all means go forth and be happy. We won't 
condemn you because you have no sense of rhythm.
