How many of us are truly satisfied with their systems?

It is possible for some to be truley satisfied but probably out of reach of most of us....

Master Po: It is written in the 'Tao Te Ching', "Under heaven, all can see beauty as beauty only because there is ugliness. All can know good as good only because there is evil. Therefore, having and not having arise together. Difficult and easy complement each other. High and low rest upon each other. Front and back follow one another."

Caine: But Master, do we not want all men to know our peace, our joy?

Master Po: Would you make the whole world a temple? Be like the sun, and what is within you will warm the earth.

Well I was satisfied, then the air conditioner came on for the first time this season. Such struggles (LOL)  

Problem is, if we hit the pleasure button of new gear and more pleasure comes out..the monkey tendency is to hit that button again. Harder. With a stick. Or dynamite. To die like little cocaine mouse, sittin' on the switch -with the new wire in his head.

The whole world is a temple, just a different one.
Sun can also burn. Master Po was idealist.

It's like speaker wire. I was a high end audio dealer about 30 years ago. I sold speaker wire from $1.00 a ft to infinity. Speaker wire will alter the sound of most systems. Which one sounds best? Some are obviously better then others but many people will like the sound of lower priced cables.
Same thing applies to any part of your system. On any day, one amp might sound better than another but in most cases it just sounds different. 
Pick what you like and enjoy it. I lean toward the "British" sound and enjoy my system. If you are going to upgrade, be sure you are getting an improvement and not just a different sound.
