Really satisfied???

Rest assured, you can always find something that sounds better than what you have. The quest is half the fun! My suggestion, when you find something you like, take a break and give yourself time to enjoy it. Technology is going to improve; it’s inevitable. When you’re ready to explore again, and you have the funds, it can be crazy exciting to try new things. However, I have discovered, after 17 years and dropping more than 500K, the more expensive your system, the more it’s going to cost you to upgrade. When you reach your spending limit, then it’s time to stop looking. 

You have a system I could only dream of having.  Several things I have learned.
1. Some people are never satisied. They want a different system because they have much money and this is a hobby. Why not?  It may be they just want a change in sound.  
2. Some people will be critial of any system no matter the cost and never be satisfied.
3. For listening pleasure everyone has an opinion.  It does not make their ears any better than yours. It all boils down to what you like and that is all that matters.  
   I am sure there is always something better somewhere?  Again, are you happy with your system?  Try room acoustics  before changing it out.

After almost 40 yrs of involvement in this hobby the most important thing ( for me) is the spectrum roughly between 200-400 hz.  If a system (regardless of quality) is washed out in this area I cannot get "into" it and it loses it's natural potential. Jim Smith of "Better Sound" and many others have mentioned this. 

Count me in the really satisfied camp.  Still like to dabble and hear new things.   You never know...
