If there is one thing you could change in your current system. What would it be?

The question has been posed many times before. I will respond as I have in the past.

I would change nothing with the component system.   However, living in the overpriced and overrated suburbs of NYC, with extraordinary real estate and education taxes, my listening room in my small home is the untreated living room, on a suspended floor system.  If I move out of the area in retirement or otherwise hit the numbers big and stay, I would have at least have a dedicated treated trapezoidal listening room, possibly designed ground up with a solid foundation, no parallel surfaces, vaulted ceiling rising front to back, and four dedicated 20 amp lines from a separate breaker.  Oh … to sleep, to sleep, per chance to dream (note I left out the die at my age).

@deep_333 Yes, the Great Lake region of NY offers much better value.  Had a job opportunity at B&L Rochester in the late 90’s that I turned down and was amazed at the value.  I would have my room there, plus lake front and pool.   In-law family ties prevented the move.  I do not have fear of moving for retirement.  The same family ties are still the issue.  In my area, while not the most dear in the country, real property is over $650 per square foot, and probably average for large city US.  Taxes are an average of $11-12 a square foot and depending on the age and lot size.  Insanity.   The town offers a low cost country club and excellent educational system, but it’s still tax insanity.  It’s time to say arrivederci NY suburbs.
