Sweet topic!
I have had LG Advents for over 40yrs but just recently assembled the double stacked arrangement. Wow is what i say! Everything is relevant to preferences of the listener so this setup is not all things for all people, but i can't imagine that anyone who likes to listen to music could help from at least enjoying their favorite recordings through stacked Advents.
At this time I have mine running through my Sansui 5000X. 85 wpc @ 4ohms
