Atma-sphere MP-1 or MP-3 What are the sonic diffs

The MP-1 is going to be more resolving with a lower noise floor...thus creating a larger and more refined/detailed image.

People pay a large premium for a relatively small perceived difference.

Dollar value of the performance improvement is a judgment call that only you can make.

 
A recent thread in the Amps/Preamps forum includes comments on both the MP-1 and MP-3. You can find it here: Atma-Sphere MA-1 amps.

There are fairly significant differences in circuit and parts that account for the difference in cost.

Thanks for both responses. The thread Jtimothya listed was a particular help.
