He's funny in his presentation, yes, and maybe a little arrogant too, but a LOT of what he says is absolutely true, IMO. It seems that the most offended/outraged on here are the ones who have lots and lots of previous posts - you know who you are.
It's not arrogant to say that some have, or can, 'hear' 'better' or 'more' than others, or rather, have a more experienced ear. eg. I have a good friend who used to be an importer/distributor of 'high end' equipment. HIS system sounds awful (to me), and one reason, IMO, is that he has his speakers, which are designed to be used well away from the wall, have their backs up against it, and one is close to a corner! You can imaging the awful bloated, thrummy and ill defined bass, and the effect that that has on the rest of the frequency range, yet he likes it and thinks it's fine. No accounting for taste, or hearing experience, or willingness to experiment with speaker positioning, which is CRITICAL.
The BS that's talked about, a LOT, on this forum provides a lot of humor, for me, and I'm sure for many others. Speaker cable risers does it for me - REALLY!!! Expensive fuses on the input to a power amp!! Get a grip!
He makes a lot of sense and says things which are absolutely true, which has hit hard, a nerve of some of the self righteous, self proclaimed experts on here.
