Perfect sound Now what?

You'll never know you have the perfect system until you've changed multiple components and long for the day when it sounded as "perfect" as it once did. Then you'll find that the components you want are nearly impossible to purchase and you'll spend the rest of your life trying to match the "utopian" sound that you remember but will never match because the longer it's been the better you remember it sounding.

I'm not really heading for perfection, but I only started really upgrading my audio equipment after I had essentially finished building my 89 4Runner for rockcrawling while still being able to use it as a daily driver.

If you want to stick with audio, simply move and your system will sound different again.

First the neverending search for great music to listen to. So yes building up your music collection absolutely. Enjoying what you have that is perfect to your ears is only one aspect of this hobby.
I am also very interested in the history of audio and spend time and money learning and listening to less than perfect but fascinating vintage equipment.
This hobby is not only about figuring out an absolute perfect system. You very well know that such a thing cannot exist as long as each person has to decide that what they hear from that system is perfect. It is impossible. Cheap or costly by any manufacturer except by one perhaps and for that you must have faith.

write my book that I have been itching to write but not had the time because of this hobbie...my book will be blowing the lid off of the upholstery business. I name names..

LOL - I should have my head examined... actually thinking you knuckleheads would get into the spirit of this.
