If you could put the very finest box speakers we can currently make today, against the perfect speaker, what would the difference in sound quality be? Would the depth of stereo image be ten times deeper? the width ten times wider? would you hear instruments that you never knew existed in your recordings? would the difference be so big that it would make a Magico or kef blade sound like a toy? Just how far away are we from PERFECT SOUND?!

I have had perfect sound for years.HELLO!!
This is a question only for audiophiles and fans of Open Baffle and other exotic designs.

Most of the world is already labouring under the belief that their humble home systems are indistinguishable from real life. 

Much like those participants of the Edison Tone Tests from the 1920s and 30s.
I thought the advent of CD players ushered in perfect sound forever.
