The measurements of actual concert halls presented here https://pdfs.semanticscholar.org/e4c9/b3222f26472f6ba12e7fea900c2edb10c14c.pdf show a much more drastic drop of the frequencies above 5K than suggested by target curves such as B&K C, Bob Katz's or HK RR1 The bass roll-off is consistent with the FR of the monitors used while the drastic treble roll off appears to be the hall response. I recently frowned at the measurements of an expensive Audio Research amp (see Stereophile) but this, and some solutions blamed for rolloff, would it be filters cables or what have you, might well answer a respectable quest. Respectably ? Personally, I simply created new convolution files to mimic SI R2, preferred by assessors cf https://users.aalto.fi/~ktlokki/Publs/JASA_lokki2012.pdf Although I can't say I suffered from brightness with my previous filters, the first impression is very good and paradoxal : more precision in instruments placement (while I had in mind that more treble favours soundstage)
