Is it live or is it?

Try small amps and big horns at home.
And try not to scrimp. :)

If your home listening space were the size and shape of a concert hall venue, then you would probably use a horn based speaker array at home. If your home listening space is that of a typical domestic room, then there are more suitable choices. And yes, there is a difference between music production and music reproduction.

Why would one pay large amounts of money to go 'hear' loud amplified music at concerts? Certainly not for the 'hearing'. It is all about begin there, nothing else. Do I go to live concerts? Yes, but only ones' that are in small settings where there is no amplification, these are mostly small jazz clubs. A perfect example of one such site in the Dizzy Club in Lincoln Center. You hear real live music.

The main reason people go to rock concerts is its a social event. Thousands of people waving their arms is unison is more like a Nhurenburg Rally than a musical concert.

I thought the main reason people go to live rock concerts lately is to stand there and try to record them on their smart phones...The last few concerts I went to, I had a hard time seeing the performers on the stage, due to a sea of hundreds of people in front of me all holding their phones up in the air!
