Whichever you choose, Linestage speakers rule, as long as you have the space to let them breathe .Some of the best I heard at Axpona were linestages. They beat some of the megabuck speakers I heard.
The big Gensis are back, but what about Arion?
Noteworthy to me in Stereophile is the release of the Genesis Tribute speakers. $125K invocations of the IRS, minus the bass towers.
Honestly though before I shelled out that much money I'd check out the Arion Apollo speakers first. The low crossover point AMTs they are using solves all of the problems of the original IRS.
