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.

I have an S30. Went from mk 2 to 3.1.
Definatly, worth it. Lower noise floor though I didn't think that the mk 2 was noisy. Better bass. More space between the performers.
Even my wife, who loves music and tolerates the hifi stuff noticed and was inpressed.
If you like the amp the uograde is a no brainer when time and funds allow.
Thank you for the response. The only thing holding me back is the possibility of being damaged in shipping. The upgrade cost is very economical.

Thank you again
I had the update from the Mk.3 to Mk. 3.1 done to a pair of silver edition MA-1's. The noise floor was lower and the imaging was more precise, wider and deeper than the Mk. 3. It's cheap and very worthwhile.
