MartinLogan Ascents/Quicksilver M80 monoblock amps

I do not have direct experience with the ML ascents, but all ML speakers are very similiar, so ... I use a VAC 80/80 (same powere as your Quicksilver)with Martin Logan Aerius i and it is a great match (much better than the more powerful Krell 300i which I originally used). My neighbor matched his ML Quest Z's with an AR 100 watt/ch tube amp (in a hugh room) and it was, again, great and much better than his original Aragon 200 wpc power amp. So, in terms of power, I don't think you will have any problem, but you might not get the same bass control as a very powerful ss amp (>200 wpc)

The M80's will do just fine with the Ascents - later you may want to biamp them with a SS on the bottom and the M80's on the top. This will bring the Ascents to a new level. I do this with my Odysseys and a Mcintosh 2102 (tube) /Mac 352 (SS). The Ascents are a little easier load than the Request and a bit more efficient.
