What does 90% of the Absolute Best Sound Cost?

I have right at $50k in my system.  Seems like a lot, but people spend considerably more than that on pickup trucks and large SUVs. I get a lot more enjoyment out of my audio system than I do my vehicles.

I have no idea what percentage of sound quality I get compared to the ultimate system.  It sounds great to me and I don't think I need the ultimate system. 

If you eliminate the hype, the sales pitches and the peer pressure, you'd be surprised at how good your system can sound.  Once you step outside yourself for a moment, you realize that it's all rather ephemeral and like already mentioned, relative. 

It's like all addictions in that there's that reward at first listen, and then it fails to maintain the high, and then it's on to the next hit. That's not being a lover of music.  

So, what does $50K get you? Sound that you'll enjoy or even fall in love with. The question is, will you allow it to as long as you have it, or tire of it because, reasons. 

All the best,

Ah, great responses.  I wish I could "like" and "laugh" at them.  Yep, this is a very subjective topic and, of course, the listening room - size, dimensions, build - is a major factor.

And I have to acknowledge that the listening experience goes beyond the bare acoustics.  I like how my equipment looks and feels. I like nice furniture and lighting.  And a bar cart with a few choice adult beverages doesn't hurt.

Trust me, folks ... it’s the room AND the power.

As to the room, I have a square, 10x9x8 converted upstairs bedroom for dedicated listening, which is an awful configuration for sound. Left untreated, the sound is absolutely horrible, and I mean "fingernails on a blackboard" horrible. Before I gave up completely or continued on the component upgrade merry-go-round, I implemented corner bass traps, rear wall absorption, and side-wall first reflection point panels. I’m very happy with the results.

As to the power, I determined that there was a lot of dirt in the lines, but dedicated lines were not feasible. So, I got items that remove line hash at various frequencies, and series mode surge protection. Those did the job ... sound clarity and headroom have improved dramatically. The neat thing is that I no longer have inconsistent listening sessions where the sound is great on one day and not so good on the next. Addressing the power issue is just as important as the room.

Of course, quality components are essential and don’t have to cost you an arm and a leg. However, failing to address room and power issues, no matter how good the components, can be fatal to the listening experience. So, before the OP goes spending a lot of dough, I think that first scoping out the listening environment is critical to good sound ultimately.

This is subjective based on room size, room acoustics, and the audiophiles ability to discern subtle differences in sound quality between brands and components,

for as you go to higher price point equipment, the absolute value of the performance/price ratio becomes smaller.  Differences perceived important to one listener may not be important to another.  That said, from my personal perspective a spend of around $75k should get to 95% of the best of the best.  If you buy preowned you can take 30% off of that spend.  To me, I believe my system is at the 95% performance level at a retail cost of around $90k and a preowned cost of about $45k.  I would have to double that spend to achieve a 2 or 3% improvement and much more because my small home and listening room would need expansion to accommodate the equipment required to achieve improvement.   My home is my limiting factor.  My weakest link now is my server/streamer where I would need to double or triple my spend.
