An unscientific poll: How often are you happy?

What percentage of the time do you just break out in a smile and thoroughly enjoy the music *and* the sound when you fire up your system? 10%? 50%? 99%? (The other times: you hear something wrong, something lacking, needs tweaking, needs upgrading, colorations, distortions, you hear a noise, a tube might be going, not musical enough, can't suspend your disbelief the way you want to, your expectations are disappointed, it doesn't sound like you remember the dealer's system did, doesn't sound like you remember your friend's system did, you made the wrong move with the last upgrade, you doubt the money you recently spent really made a difference, the recording is too flawed, you wonder what it would sound like if you changed this or that, you enjoyed it more in the car, you question whether you've truly got your priorities in perspective, etc...) Give your %, and list the approximate $ investment you have in the system (specify new or used valuation). Mine: happy about 15% of the time, valuation around $17,000 if all bought new. Conclusions - if any - drawn later...
