MHDT Havana and Eastern Electric Minimax

Has anyone heard both of these DACs at one time or another. I am still considering a DAC, and was all set on picking up a used Havana, until I was informed that adding the Havana to my de Havilland Ultraverve 3 preamp will be too much, and would produce soft bass.

The gentlemen thought that the minimax may be a better match because of its greater neutrality in comparison to the Havana.

Any thoughts?
