Yea cause you know, your speakers and audio system has to be worth at least $5000 in order to be able to post here, or care about sound.
So you got your panties wet because this thread is exactly about people like you? 🙂
The point that you've obviously missed is, this is a high-end audio thread, on the Audio/Video board.
Nowhere have I said that someone "needs" to have a 5k system to "care about sound".
However, it's clear by your purchase of 100 dollar speakers that you DON'T care about sound, at least..not that much. Or you don't have very discerning ears. Or you don't have the disposable income, or are simply cheap, or whatever.
But whatever the reason, you don't care enough about sound quality to put any more money than what you have spent.
And again, there's nothing wrong with that. If you think your Polks sound great and you don't feel the need to spend anymore, fine. Enjoy them. Just know that some people DO think that it's worth spending more to buy speakers that absolutely sound better than any 100 dollar Polk, and there's nothing wrong with that, either.
Just like there's nothing wrong with someone who desires great sound, and has the money to fulfill that desire spending a crap load of money on better speakers. Buying a 3000 dollar speaker might not get you as much improvement as going from your 100 dollar Polks to my 1000 dollar Definitives, but who cares if someone who can afford to wants to buy a set?
That's what and who the high-end stuff is for. Sure, there's diminishing returns. That's the case with everything. Sound, speed, video.....the better you want, the more you spend, and the more you proportionally have to spend to get small increases as you climb that ladder.
I'm not going to bash someone who wants to spend 5k for a Sharp Elite 70" TV. It might be just a hair better than a 65" Panasonic Plasma. Not worth the extra 3 grand to me, but if someone else thinks it is, go for it. But I'm not going to sit there if I had a 65" Toshiba LCD and claim there's not that much difference and it's not worth the money, either. That's basically what you're doing.
