I have the MA Silver 100 g6 in my secondary listening room, powered by either a Marantz PM17 or a Cary SLI30. The Marantz is about 90 wpc, the Cary is 30ish wpc.
These are my 3rd pair of MA since i moved on from PSB about 8 years ago. I like them for their balanced sound, and their imaging. The S100 rivals my RX6 for bass power, although the rx6 is in a much larger space.
My secondary listening space is a bonus room, about 15’ x 20’ with an irregular ceiling. The S100 can easily overload this space, so I listen at moderately low volumes.
I also like the cabinetry in the Silver series.
I can’t comment on the comparison to the Elac’s, I’ve never spent time with those.
would I buy the S100 again? I would, but in my listening space, I would first audition the Silver 50 g7.
Best of luck,
