Wow, this thread is much longer than I thought it would be.
Does price have anything to do with quality or sound? Of course not. We'd all like to think it does, but pricing strategies usually have more to do with how the market perceives the product and how much value the buyer places on it. Hopefully the market you're in recognizes quality, but we all know that they generally don't. Certainly generalities exist, but you can't tell me that a $900 bass will always be better than an $850 bass, because that's not what price indicates.
FWIW, there is a thing known as Premium Pricing, where prices are set artificially high to create the perception of quality. If you've ever shopped for motorcycle gear *cough*Icon*cough*, you've seen this in action.
Humans are easily fooled, and marketers are paid to fool us into thinking that the brand they're marketing is a quality brand. Price is only indicative of how much money the seller is asking for.
