I have noticed the same issue.

Up sampling x2 in MS200, yellow light on 5200SEs results in an MQA soundstage which isn't as clear as when up sampling is set to 'direct' in MS200, 5200SEs yellow light off

More listening is needed but up sampling in the SEs is clearly either just better than in the MS200 or the up sampling in the MS200 is messing with the soundstage...

The fact that you have similar issues using an 861 is curious indeed.

Anyone else noticed it?
