Many variables. Type of music being a very important one. I have never heard any system capabable of reproducing the almost physical low bass energy you experience live in a Jazz club. Thenagain, solo instruments and small acoustic ensembe music can come pretty close in a high end system. Recording quality is also a huge factors. Ironically, the closest to "the real thing" I experience in my system is actually a multi channel surround sound SACD solo piano recording on the Norwegian 2L label (Mirror Canon) - no Chopin though. This is as close as having a Steinway in my room as it gets.
I also remember walking in a show floor and believing there was a live ensemble playing around the corner, only to find out they were playing a studio master tape over JBL monitors - so 5% seems a rather conservative number.
