Seems I'm really done!

Hello John,
You posted words of wisdom  based on many years of listening  experience. One pertinent factor for long term contentment with one's system is what is the ultimate objective?  You mention that you were perfectly happy with a system set up but then you become bored. 

If genuinely happy  why the boredom rather than continued happiness with a  well conceived system?  My humble guess is perhaps the goal was perfect sound as opposed to pure music listening enjoyment  and emotional involvement. If the objective is the latter then once reached there should be no sense of boredom.  If the goal is the former then long term contentment remains elusive  (something is always better just around the corner ). I absolutely recognize that for some the pursuit of the unobtainable perfect sound/system is what motivates them. No right of wrong choice,  but people need to define what is their end game.

Hi David,
We all can agree that actually listening to something is the best method to make a sure buying decision. However this isn’t always practical or possible. I’ve been able to obtain first rate products based on impressions posted by trusted experienced members of this site. The SR Black fuses being the most recent example in my case. Current discussion of the SR Black and Cerious Graphene cords has caught my attention.

Just fine tuning for a system that has been intact nearly 7 years (source, electronics and speakers ). I have no plans to change the system foundation, just tweak it. It's funny but very rewarding that replacing stock AC wall receptacles and component fuses with better quality versions truly matter. 
Charles,

John,
Thanks for sharing your perspective. I was curious about your specific audio goal.  I assume that you're satisfied with your current system ☺
