Where was the best reproduced sound you ever heard?

Schweikert Ultra 11 with the VAC / Esoteric /Kronos setup they bring to CAP in the large Atrium room. Concert hall feeling. Alone the Masterbuild cables were close to $250k, around $1M system. 

Certainly my own system as over decades I developed, vetted, tweaked, and generally made my gear heap conform to my personal taste, which results in an astonishingly well sorted sound in my surprisingly great sounding room. Utterly personal of course as most of my friends don’t care at all, and I don't have a stream of audio geeks coming by with their preferences in their addled brains. As a certified "knob turner," working musician and concert producer/sound mixer, my taste has been formed from live music which I can instantly produce by playing an instrument, although listening is easier. Seriously, you have to take a uke off the wall, tune it, take a guitar out of its case...check the humidifier, change batteries in tuners...click a switch on an amp...it’s just so much.

If you ignore ticking noise from turntable, this is the second best reproduced sound that I had listened.

I did not record the very best one so I could not show it here.

The one on 31 minute could be the system OP had listened.

This one was unexpected.  At a Stereophile show in Manhattan in 2005(?), Roman Audio Centurions powered by Krell gear.  We put on a Brad Mehldau JVC XRCD, a sampler, "In the Wee Small Hours of the Night".  About a dozen people in the room, and nobody said a word, or even breathed very loudly, through the entire 6+ minute cut. Even when it ended, people were just still gobsmacked and silent for another 10 seconds.  Too bad the poor guy couldn't get the brand off the ground.
