Qualities Of An End-game System

My end game definition is when I close my eyes , I am no longer listening to a stereo system. But Iam right there on the actual venue of the concert hall.I no longer thinking of buying anymore gear or cables.Much like looking forward to buy more music.

"End Game" seems like a variable term defined by expectations. reaching expectations is the end. so my ’end game’ would be different than yours.

There is a catch there...Expectations may be dependent on what a listener may have had prior exposure to, what he even knew is possible (or exposure to something that gave him a feel for what is possible). If he didn’t have any concept of what is possible, he wouldn’t know any better.

The perception of disappearing speakers is fairly easy for someone who’s been around (knows some stuff). Making the room disappear takes more work, investigations into room acoustics, planning and investment, as you may know.

Making the listener himself disappear/shutting his mind’s nonsense down.....making the actor recede so only the act remains requires something serious. Throwing cash at anything/spending cash in the wrong places doesn’t get one there.

Attaining the attributes of the end game system as described is easy just buy a pocket radio with ear buds and some LSD.

My wife has been trying to make my speakers disappear for the last 10 years. 

End game is theoretically mythical-nothing is perfect-but practically when you reach the point where your system is satisfying and enjoyable and you have spent the all the resources you are willing to spend to make further improvements. I'm reasonably close-still a couple of improvements I intend to make to my system- but I know it doesn't mean my system is approaching the ideal. It just means that in a hobby where you generally get what you pay for and more better usually means more money I have just about reached a balance of satisfactory performance and what I'm willing to spend. Not a bad place.
