We are all different with varying levels of curiously and open mindedness.
Yes, exactly my point, we all are different, with different tastes and preferences. You can order a steak rare, medium rare, medium, or well done for a reason- what might that be?
There are people who swear by tubes, vinyl, and horns. There are just as many people who swear at them. Class A is best! No, class D! Ribbons! Horns! And on and on it goes.
So it is only reasonable to state that something that is "better" to one person may only be "different", or worse, to someone else. "oh, I can see 10 things I can do to take it to another level" is not going to be truth for everyone, despite the manic pleas of "just trust me, I have been doing this for years". Every time anyone asks for any objective proof, the answer is always "trust your ears". Well, I do trust mine, but I don’t take your money and tell you to trust my ears, I say trust your own. If you want to pay someone money to mess around with your equipment based solely on blind faith, a wish, and a prayer, without any basis is tangible reality, go ahead. Like old PT said, there’s a sucker born every minute.
You don’t see people like Bruno Putzkeys asking you to "just trust your ears". He publishes the results of his efforts. These tweak people are like parasites that live off the work of real engineers- what do they produce? Nothing- they take someone else’s work, wave their hands around and pronounce "I took it up another level". If they are such audio wizards, why don’t they have a go at designing and building something of their own? No wonder it’s called snake oil, fraud, and a con. They pray on the insecurity of others, nothing more. And heaven knows there are few groups as insecure as audio nuts. Put your cd in the freezer lately?
