Pop noise, B&K Ref50 s2 still have it??

I'm looking into purchasing a B&K Ref50 s2 pre/pro for my upcoming HT set up. I've read some reviews of other Ref50 s1 owners saying about the thump when switching sources and volume drop off when play DVD. Does the Ref50 s2 still have these problems or B&K corrected it already?

Thanks for help,
I've had one about 3 weeks now and no such problems. It sounds great to me.
I have the series 2 and have not heard any popping. A friend has the series 2 and has had minor popping in the menus. It sounds great but I am considering changing equipment as I do quite often.
