How many of us are truly satisfied with their systems?

I agree with mazian. I am happy with my system, but am always planning what I think will be improvements. I don't let that get in the way of my enjoyment though. Once upon a time I did. 

I  am truly happy and done with my main rig but I may upgrade  the Integrated amp in my secondary system to a more current McIntosh.  That's it, as I am now retired, I don't have as much disposable income as I had when working.

I know I am not  now.  but once was.

Im not satisfied thats why my system continues to evolve and improve through the tweaking and incremental improvements that add to the total sum of the desired SQ Im trying to reach.

Also being retired and funds not being what they once where the biggest economical improvements continue to be through improved electrical current being provided, last great tweak was installing three Bybee IQSE in my electrical panel as suggested and for less then $300.00 the improvements are significant.

No manufacturer will ever say, "I sell you something that you do not need." He will always say, "I sell you a thing without which you can not get along." This transformation of the superfluous into necessary creates the so-called consumer.
