What's your profession? Age?

I'm a Civil Engineering college student at Cal Poly, SLO
20 years old
Jazz musician for the past 10 years give or take.
And working hard to support the hobby!

At 45, and an Oceanographer, I've been interested in hi-end audio only several years. During this time upgraded numerous times and have arrived at a 2 channel system worth approx. $12k and Home theater worth $5k. At this point in my system, I estimate that additional expenses toward upgrades wouldn't be commensurate with the few percentage points in audio sound obtained. Any other perspectives on this?

Well, I am still 42, and still a forensic psychiatrist, but since my original entry in this thread a couple to things have changed. First, my system now retails for around 16K (though I mostly bought it used for considerably less). Secondly, my idea of where diminshing returns start is now at around the 30-35K retail point. Lets hope it stays there.

55. Manager/Designer/Inventor. $95K. Not done.

I'm 24 with a science degree. Mostly chemistry and environmental science. Audio is almost the worst superfund case I've seen. 13k and counting.
