@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!
