How much power is needed for Martin Logan Ascents?

I would check the minimum impedance; the Spires go very low, these may also. With many speakers it is not the rated power so much as how they handle low impedance loads.

Sanders ESL amplifier.

I owned a pair of Ascent i Logans for 2 years and powered them with a number of different amps from original atma-sphere MA-1s with speltz auto formers to 2 Rotel 1090s (too bright) to Jolida 300A monos to a Mesa Baron which was the best amp I had on those speakers and the only piece of audio equipment that I wish I never would have sold. These speakers like power, and Stanwal is correct they dip to below 2ohms up in the higher end of the frequency spectrum. I could never get the bass to integrate with the panels to my liking and believe me I tried. So I ended up selling them here and have not looked back.

Also Pal you didn't mention what your budget is, that will make a rather large difference in your possible choices. I will say that I just picked up a Wyred 4 Sound ST-500 250wpc class d amp and am totally impressed with this amps sound. It should powre the Ascent i speakers just fine and is around 1k used.
