Having both speakers in my home, in my system there is no comparison. The newer panels have better definition and extension of the highs. In my opinion the older panels are the ones that have a coloration that could be called "plastic". I'm comparing it to the Odyssey which sounds different than the Ascent. In my system I've yet to hear a "plastic" sound, and I'm using a Levinson amp? The only speaker I can remember that sounded plastic that I owned was the Acoustat 2+2, which I really loved overall! If you can find a good used pair of SL3's grab them!
How do the Martin Logan Ascents compare to the
Older Martin Logan SL3s and ReQuests ? Do they sound better than the SL3s, better than the ReQuests and how so ? Any input would be appreciated. Thank you.
