Audio should never become a hobby. Because it cannot make you happy. But music can make you happy. I visit many people with highend sets who were struggling with there set. Then there can come a moment you want to give up. Often it is caused by making the wrong decisions togheter.
When you do not know the properties of an amp,speaker, cable, conditioner, source etc. It Always will be difficult if those parts will work well togheter. The acoustics of the room and the properties togheter of all the parts will give you the overwhole sound.
In almost 16 years of doing tests in audio I am aware that most stuff in audio it not that special or worth the money. The real good stuff is very limited. The change of a well balanced musical set is small.
It starts at shows, normally you listen to flaws all the time. Caused by using stuff who do not work well togheter. Or the level of the stuff is not good enough. But it is still being bought by people. And sold by who?
