220 pro - first hours and disappointed

[Cylob]

I do not remember much about burning on, me D200 is three years old now BUT I have noticed that the SQ changes while playing, especially fron syand by and for the first half an hour approx. The SQ stabilizes when the A amp temp reaches mid 40s.

Check it out during your next listening session

Exactly! That's why I leave mine always on. I think it's a bit more harsh sounding when cold.
Not sure if it's the same with the 220Pro though.
