The Difference Between Smart And Dumb Upgrading:

If you have an open mind, you'll believe (with skepticism) most audio upgrades and tweaks

So both the smart and the dumb upgraders will eventually do the same things - audio fuses, CD mats, spikes for equipment with no moving parts, resonators, magic pebbles, de-static for grounded conductive parts (just in case, if you do not understand why this is pointless, please do a search), pulse generators, parallel power noise filters, power grid vibration dampers, and anything requiring nuclear or quantum physics (probably relativistic physics too), Schrödinger's cat, Klingons, Pikachus, and Yagami Light.

But the main difference is that the smart upgraders know where that $200 or $1k should go first. And it usually does not involve Klingons.

So, if you realize that you've been spending extra on stupid things which could be better spent on more realistic things, this is a sign for you to stop. Fortunately for you all, those who enjoy reading my blog, you most probably haven't, and for those who do realize, now you know. For those that are not reading my blog, well, they can't see this anyway.
