If by "big" music refers to orchestral music ...... that few exhibitors have the courage to play it.
As someone who benchmarks only to classical - this Wednesday I went to Beethoven's Cello Sonata 2 and Shostakovich's Cello Sonata, today I saw Valery Gergiev conduct Stravinsky's Symphony in C and Scheherazade, Tuesday I will watch Haitink and Emmanuelle Axe perform Beethoven's Emperor, and Saturday Sarah Connolly perform Mahler's Das Lied - I have never seen any digital come close to Lampi's performance on any classical especially orchestral. The bigger the tutti, the better it gets (with the right tuning with valves), as it differentiates the tone of various instruments giving them their realistic density, space, and decay.
Lukasz says that the Pacific excels on the peaks and should be a much bigger step ahead. Tbh I found the Big 7 sufficient. So I am equally frustrated to see Pacific playing small scale music through small scale speaker at shows. I also hope dac displays at show have a bit more than their own streaming catalogue, which always frustrates me in Munich as this means the tracks one can play are usually restricted. Having a CD transport allows one to use one's own CDs. Hopefully the Harrogate show (which I will have to unfortunately miss) has more classical flowing through the Pacific, Kronzilla, and the hORNS Universum, as all those excel at orchestral.
