Aesthetix Atlas + Calypso

Hi,
I am thinking of changing my Classé CA2300/CP800 for the Aesthetix Atlas/Calypso combo to drive a pair of Magnepan 3.7.
Objective is to have a more lively sound, with more "body".
Any feedback on the Aesthetix combo would be most welcome such as:
- Is the Atlas providing enough current to feed the maggies?
- Is the combo reliable?
Thanks
