Good stuff guys. I guess if you do not like live music then you would search for more sterile recorded audio but in the end all musicians are trying to get that performance to come across as if they were playing to you. Hence that is what I would consider the perfect system. The soundstage that presents itself like the folks are in the room. For sure some systems sound better then some rooms as acoustics are not the best at many venues I have seen shows at. Places like Royal Albert Hall, The Beacon, The Met , Carnegie Hall and many many other small theaters I have seen shows at have incredible acoustics if you are in the right location in the venue. The old Palladium, The Lone Star, CBGBS, Commack arena just to name a few Horrible acoustics. Yes rooms all differ, acoustics all differ and some venues are absolutely horrible, outdoor shows are not going to provide solid acoustics as well.
As noted , I already have horn loaded Klipsch Fortes with a few choices of amplification. I know Klipsch strives for the live sound and they get pretty close . At low volumes just incredible accurate sound out of my Fortes. I would go for La Scalas if it could fit them as maybe I need that to get to where I want to
I will look into some of the other speakers mentioned as well but still have the question, why not a small array for home? There is a guy that built a mini wall sound and now is building another larger one. The mini system probably would be something I would dig. It is built for instrument separation as was the original wall of sound. If you haven't followed that its pretty cool . Do some searches
