I received my SS upper platter yesterday. Comparing the duralumin with the SS I find the SS to be leaner and meaner and the duralumin to be a touch softer and warmer in presentation. I felt the mid bass on the duralumin platter to be a touch bloated for lack of a better expression. The SS seems to go deeper and has a firmer grip on the bass. Upper mids through treble is noticeably more extended than with the duralumin version, ime.
I feel there is a bit more jump, sparkle and presence with the SS vs the duralumin. It definitely changes the tonal balance of the AF1 for better or for worse depending on your system tonal balance and preference.
