When is your Hifi good enough?


Just wondering what makes people tick in regards to determining when things sound "good enough"?

For me I have a vision in my mind of how things should sound based on what I have heard over the years.  Once it sounds that way, I am done.   I can still enjoy listening to other sounds or sounds that omit some things I might want otherwise but if I do not get regular samplings of "that sound" I probably start to wonder.

1. Lack of any audible distortion,

2. Good textural variety (to me, tubes kind of smooth everything out),

3. Even tonal color and density, and

4. Adequate dynamics (I like a lively sound i.e., P.R.A.T.).

Yep, that'll work...

It’s good enough when you either run out of money or interest. Otherwise, it can always be improved. If you’re interested and you have the money. 
When you can't think of anything that will improve on what you already have.
 I don't own the 'best' of anything, but I have invested a lot of time in synergy and set up of what I have. I often sit and think how nice some other stuff might be, but then, when I really think about it, I can't think of what I'm really trying to get out of my system. I'm happy, I'm done. Now if I could just lose the fantasies. 

I solve this problem by re-directing my energy to finding new music. 
chayro, but if its "good enough", why keep at it?  That would seem to indicate that in fact it is not for whatever reason.
