I will agree with "Rushton" that the problem is not with the Atmasphere. These amps remain my favorite after listening to many others. They also work on many speakers - not just electrostatics (though they sound absolutely superb on these). On my Magnepan 3.6's they sound outstanding. And, Maggies are probably the last speaker that many dealers would recommend them for. Now to be honest, it did take the auto-transformer to provide the superb sound but, this was just a simple matter of impedance matching the Atmasphere to the Maggies.
