Well, the timing was right for internal upgrades. It was either that or pull the SDA 1C's apart and upgrade the internal wiring and I didn't want to be without speakers for that long right now. I had such a huge improvement in sound quality upgrading my Belles 21A pre with Mundorf Supreme caps I decided to try it with the 350A. So I pulled the box out of the closet and proceeded to unpack and set it on my work bench / dining room table. I forgot how heavy this thing was!
Here is the left bank circuit board with the 15 uF Dayton cap and the two Amphion 2.2uF caps
Not bad, just a zillion screws. The Amphion 2.2 uF caps were about the same size as the Mundorfs I was replacing them with so it was an easy swap. The 15uF Daytons on the other hand were MUCH smaller so I had to drill out bigger holes for the leads and new holes for the zip ties since for some reason there were none. All in all it probably took me 5 hrs with inspection, clean up and throwing the ball for my dog.
Here's a shot of one channel board with the caps reinstalled.
With only a few hours of burn in I'm liking what I hear

600v the only voltage that the mundorfs come in? That would be why they're so big.
