I can also tell you that better cables- i experimented with Transparent's- will
provide more bass if you choose to upgrade. either way, Aerial Acoustics is as reputable as Wilson or anyone else IMO. as long as they are properly grounded
you are "done" buying speakers for some time. I made the "mistake" of upgrading from Eggleston Andra-II's to a much larger/more resolving speaker and i wonder to this day if the trade-offs were even worth it- sure, what i have now is better, even amazingly so. But- the Egg's were so well suited
to my listening room that i often miss them as well.
