I am convinced that our ears and our brains are the worst enemies to our wallet when we get that itch for upgradeitus.

I think it is psyco-acoustic need for change that drives us. You go out and buy a setup and tweak and change until you get something that you convince youself is much better sounding than whatever you had before. And you live with it for 3-5 years and then suddenly your brain starts to tell you that it isn't good enough and there is something better out there. Be it from reading a review that said Speaker X is the best sounding or that Amp Y just improved the sound night and day. So suddenly you convince yourself that what you have isn't cutting it.

So you get into the position that Bridgman is in where he is testing two speakers that are different from each other. What one is better? Neither. they are different from each other. If you had been listening to the same sound feel for the past 3-5 years it is bordum in your brain that convinced you to change. So you get something new to change the sound that was perfect before but suddenly now is not.

Likely if you forced a change in the placement and treatments inside your room every 9-12 months, your brain will never get use to or tired of what you have and you could likely save yourself a whole load of money.

This of it like toys for a cat. If you leave your pet cat 10 toys out to play with, then it will play for a few days and then get boarded of all of them. If however you put out 1 toy for a few days then put it away and swap it for a different toy, then the cat would be entertained forever. by the time you get around to the 10th toy it would have completely forgotten about the 1st one and as far as it knows, this is a totally new toy.
