Audio is a lot more than only building it. Even at many shows often a subwoofer does not have a belanced sound as it should have. Even when the manufacturers are there at the show.
Often at shows they tell a nice technical story ( at their own frequency), but the demo is not even convincing. Hearing is believing.
They should tell about their products on the same frequency customers think about audio.
What do I hear....this is what counts!!
The people who make things often use a few brands to test. I have often asked brands like Pass Labs, Nordost and Audioquest people about their knowledge in other products of competitors. And different sources and amps they use with their own products.
I was often surprised that they knew less than I thought.
That is why I said a few times; there need to be more communication. The endresults in sound needs to get to a higher level. They need to work more togheter!!
