WHAT WAS THE BEST SYSTEM YOU EVER HEARD AND WHY WAS IT?

@aolmrd1241 thanks for the link, I wasn't aware of that.  We were listening to vinyl, but I assume the playback media doesn't matter since the effect was produced by the recording technology.  I bought the vinyl afterwards as well as the CD/Bluray combo after that listening session. I did get a lot of that 3D effect in my own system, but not as enveloping.

@calvinj I told Kurt I was pissed at him for letting me hear that system because I was going to go home and be unhappy with my system. Thankfully, that wasn’t the case :)

@ big Greg that Raidho system was that one that did. I have a greatly matched system but that thing was about 600k of top of the line greatly matched!

At Audio Alternative in Ft. Collins, CO.  You can google the name and click on the site to see both his show room and private set up. His set up includes Vandersteen7 mkii, Vandersteen subs, main amps and other equipment I am not sure of.  Listening chairs are very comfortable leather about ten feet from the speakers.  He plays only vinyl, mostly jazz.
Get ready!  The system no longer is a source of sound, but the room becomes a musical atmosphere and the sonic performance is as natural as breathing.  All in all, an incredible
experience and needless to say, very! addictive. 
I am not affiliated with Rick or Audio Alternative except as a happy customer.

It is not the most expensive that is the more impressive, the Elac combo Debut, heard in Montreal audio show, was unbeleivable for his price.
