Kinda like what Havasu said. I dont judge a peice of equipment before i use it in realworld applications. For the record, I own and use a ddm, and oscope. And I am lucky enough to have a good friend who is a tech geek and uses some techy analyzer to check my music. You are open to judge said equipment that is your prerogative, but i am one who has no issue trying it out to see if it works for what is should, and what i want it to do. The only time I play my system at its full extent is when I give a demo to someone who thinks I aint got shit. I dont compete in shows either im just one of those regular joes who enjoys car audio and are blessed to be able to afford to buy what i want. And im happy for you being one of those guys who can do it all with just your ears and eyes. As for me i have embraced technology and use it often. Now Havasu get those speakers so we can see them already
