Better sound at night?

[Jonas]

Late night is also a fine when the body /brain relaxes more.

Now you hit the other side of the coin!    Sorry for digging little deeper... Our autonomic nervous system consists of 2 aspects, sympathetic (activity) and parasympathetic (rest). It´s easy to measure these parameters with so called Heart Rate Variability (HRV). Balance in HRV is a sign of health and coherence. Noticed that it sometimes takes 3-4 tracks before I enter a kind of relaxed coherent listening state. So once I tried to meditate for a short while before the music session and experienced directly a state of coherence.
