Well, reading Audionet's propaganda
, It appears that DC coupling is a big difference technically, also the bandwidth of the scientist series is quite a bit wider.
Don't get me wrong the MAXs are better than all the other SS designs I've ever heard, but the Scientist series is better by a significant margin, moreso than one might expect at the edge of the art.
I would certainly choose the MAXs hands down against everything else I've heard if the Scientist Series didn't redefine the SOTA in SS for me.
