I agree that in all similar quality speaker levels, it comes down to listener preference. Unfortunately revel dealers of the Ultima class and Aerial dealers are quite a distance from where I live to be able to hear them at least in their demo rooms, and of course both are likely using different amps and acoustics making any decisions that are not based on your own amps in your own listening space makes this hobby challenging. Since both are at a significant magnitude higher in performance and overall owner and reviewer opinion that my current speakers I'm sure I'd be delighted with either.
