How do you rationalize audio upgrades?

I’m similarly aligned with Erik’s thoughts on this, but go one step further.

Learn about audio and figure out how to make changes that are essentially tweaks and cheap.

Ie, beneficial changes that are for the better, sonically... cost very little... and teach one much.

To figure out how to simplify the system and have that sound better. Less (gear in the path) is more (sound quality), in audio.

No, wait! We sell cables....so buy equalizers. Yes, that's the ticket...

I don’t "rationalize" my systems upgrades... because... for me... its totally... "irrational."

Desire. It’s a thing to itself, and doesnt need rationalizations. 

I'll cast my vote in with @erik_squires ...(Hi!)...

I try to do the improbable with next to nothing.

Next goal:  The Impossible with Nothing.

(....there are those that feel I've already done so with my mental state, but they'll get theirs when I've achieved ultimate control over the physical universe...)

I'll go lie down now......;)

how to convince yourself to spend more? listen to it .see if you notice a difference and if it's worth it.
