Atma-sphere MA-1 mk 3 to 3.1 upgrade

I own a pair of these amps and was curious if I could get some feedback from anyone who sent their amps in for this upgrade and how beneficial it was. Thank you in advance.

The only thing holding me back is the possibility of being damaged in shipping. The upgrade cost is very economical. Thank you again

The noise floor was lower and the imaging was more precise, wider and deeper than the Mk. 3. It's cheap and very worthwhile.
