Dc offset fluctuation on zpa 0.3

[ReneBMW]

Hello guys!

I understand that on some amps a minor Fluctuation on Dc offset is normal.
I tested it on both my zpa's, and it fluctuates +/- 3mv.
But on my ti500.4 an 600.2 and the zx475's this doesnt happen.
So is this a bad thing, is it designed to do so? (Read a post on "thermal tracking"?!)
And if this is normal, what are the digferences in design between zpa and zx/titanium?
Thanx in advance!

Nope, max 3mv up and 3 mv down.
I read someting about coupled outputs wich some older amps dont have, and the "newer" amps do.
