For those of you who had spent over hundred thousand dollars for your sound system.

If you are worth millions then $100k is reachable without any thought. . $$$$$ is in the ears of the beholder.  Whatever makes you happy is what matters.  There is a different world I cannot imagine. I heard 50k speakers that could not compete with my DYI speakers. No contest.   I expected the other way around. Not! $$$$ do not always equal sound accuracy or overall dynamic sound quality.

I have well over $100K in my main system and many more $$ in my surround systems.  I’m not bragging. I’m 68 years old and have been into audio since I was 4 years old.  To me, one of the most important components,if you want to call it that, is your room.  I can’t stress this enough.  You can have a fabulous system, but if the room can’t do it justice, you may as well have a boom box.  It took me years to learn this and I’m still working on it, although not as much as I used to.  I’ve reached the point where I enjoy listening-not trying  to make it better.  Good square footage, higher ceilings and absorbers and diffusers are the key. A $5K system can sound better than a $100K system, if your room is not compatible. Do research about proper room dimensions, absorption and diffusion and implement it and you’ll be way ahead of the game. 

I'm glad I didn't have to answer this one.

Its a psychological effect.  People will not feel good on a $300 pre amp or $2000 amplifier.  Let alone a $5000 pair of speakers.  If people hv the money, $100k means nothing to them.  I've enjoyed my system and enjoy the hobby.  I always have the conscious of the law of diminishing returns.  A $100k system will sound better than a $10k system and we probably could alll agree: but will it sound 10x better? Probably not.  

Everything is relative.  $100k to some folks is a significant amount of money and $100k to other folks is less than they pay in taxes, give to charity, etc.

I have been into my system since I was 14 - and did I ever regret a purchase?  Kinda, once I bought a NAD integrated rated at 85 watts per channel and it didn't sound good to me.  It simply wasn't creating a good sound stage.  I took it back to the dealer and bought the 150 watt integrated and that solved the problem.

Over the years, I've upgraded my system and I've enjoyed the process.  And I've enjoyed the process with friends too.

I always thought that's true for others too.
