Really satisfied???

"I think maybe perhaps" I am satisfied with my system. But then you send your transport in for tuneup and a friend lends you his PS Audio PWT and the "snowballing" begins.  You buy your own PWT because the improvement over your Audio Research transport was wonderful. Then you notice one of your Tara Labs AC cables is damaged, so you replace all of them with new Zu Audio cables. Then you get into a discussion on interconnects and replace all those with new Hero Kimber Kables.  The new PWT gets you thinking about your Bel Canto 1.5 DAC and again, your friend brings over a Bel Canto 3.75 w/ VRB power ( while your DAC is being updated) and he also brings over his massive "money no option type" Wadia DAC and you hear "magic" (and dollar sign$...accck !) and know what your system could sound like. 
All in all it's a terrible, wonderful, amazingly scary and neverending adventure we audiophiles undertake each and every time we listen to our hobby, our escape, our needy little electrical, addictive stepchild,  our version of  musical nirvana  !  In my opinion, of course.  

Hey jnovak Ive owned the Krell 20i with the delta 9 upgrade about 2 years now and couldnt be happier, Laser is still going strong, Unit is built like a tank , and has the most incredible slamming bass i have ever heard in a cd player. 

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.
