Atma-Sphere MA-1 filter cap upgrade

Hello,
Has anyone heard the filter cap upgrade (via Atma-Sphere) that available for the MA-1. What sonic improvements does it make? I have read that it helps improve lowend authority -- I have Quad 988s, would I notice this added boost?

i.e. - Atma-Sphere offers several upgrades for the MA-1 amplifier, including V-caps, caddack resisters and so forth, the upgrade I'm specifically interested in is a separate upgrade -- whereas the filter caps from the MA-2 is utilized in the MA-1 and as a result the power switches and rectifiers are also utilized.

I can't answer your question, but I will say that the Caddock resistor upgrade was worthwhile. It resulted in a less aggressive, more natural sound.

I have no experiance with the upgrade your asking about but as an S30 owner I think a call to Ralph Karsten at Atma-Sphere would get your questions/concerns answered. Ralph is an honest sraight shooter and will give you the pro's and con's without hype.
