Do we really know what "Live" music sounds like?

Deep experience with anything allows you to make adjustments. If you are at live concerts that are being recorded. Look around. Where is it being recorded from. When ever I go to a concert I look and listen to the acoustics. I look for microphones, the concert control panels. 
 

So many rock and other electronic concerts are screwed up… bad venues, bad volume control. But going to them you can learn.

My Goodness - I never told you how incredible Chris Potter was. A fantastic show. He was so giving to everyone on stage. An intimate setting in Philly  made for a VERY memorable night.

great to know you enjoyed c.p. -- he is one of my faves, tremendous talent, musicality, tone, and very likeable in how he relates to the audience as well

Back to the amplifier + speaker. If you want the system to have live music, the key is on the right pre. Preamplifiers could be very different,some very high price pre could filter some sparkle of the recording,which you do not know if you do not compare.

I am fully agree with you and you are talking the details which I do not on my prior post. Thank you!

The key word to description the while story is "imitate", we use electric device to imitate the live sound, which is completely different things ,but let you feel almost same, and let us enjoy and happy. It is the movies, and it is the carton movies, and try to tell you the real things, which is far far away.

I suddenly find a good example now. In old times, when the society is not so stable, the president have one or more than one substitutes, and they will attend some public ceremony ( Usually the substitute do not speak a lot as it will expose the different with the real one). The real one is the live music in the music hall and the substitute is the music system home,which does not matter how much expensive the devices are.

The internal principle is different, and different by far, and they just try hard to imitate the real one. That’s it.
