In other words, the same output design, with 20 transformers, plus a bit of extra current. The Magtech has one other clever trick: its regulated PSU.
I think a really interesting experiment would be to compare the Magtech against the 200 powering your Sonus Faber speakers!
Also I wasn't clear on something... with the Magtech what pre-amp are you using? Or are you using a digital volume control in the M-DAC?
