I have had 5 pairs of Advent speakers: OLA, NLA, Advent/1, Legacy II, and Baby III. All recapped and refoamed. The only one I kept is the OLA, and it is in my garage.
I have 5 pairs of EPI/Epicure speakers: 20+, 70, 100, 120B, and 150. I still need to restore the 120B and 150, but they still sound great. I regularly listen to my 20+ and 100. I have no plans on getting rid of any of them.
I have not heard the EPI 200C, but I would likely choose that over the OLA if the price is similar. The OLA is a great rock speaker that works well to play loud. But the EPI speakers edge it out for all other kinds of music in the house and office.
