I spend a lot of money there doing a full page every month, and I deal with an outside ad rep like everyone else.
On Musical Fidelity ..it couldn't be that the gear deserves it, can it? The product of the year awards from not just the US, but from the UK and Asia? Naw...it's the guy behind the grassy knoll that killed the president.
As to any reviewers likes and dislikes...I will say this. Some want to "be the first" to discover something. If they aren't, they may temper their words without even realizing it. If you piss them off, you may get a review that is lukewarm to bad. So on a personal level, yes, there can be a lot of ass-kissing.
No different than a new car introduction. You don't think that does not get special handling? Parties? Test track get-togethers? In most other industies it much worse than hifi because high end audio manufactures are small and don't have the money.
As to relationships and gear getting hand delivered, If you were the owner of a small company you would not make sure everything lined up? You'd be dumb not to.
Lastly, some people are fans of marques. I like BMW. In fact I LOVE BMW. So when they come out with a new model I will have interest and a pre-conceived feeling of its potential. I have a Chrysler Town and Country minivan too (I have to). My last one was a piece of crap, and though this one is better I still cast a suspicious eye. It's human nature.
One last thing. I've been in this a while, and when guys get into ultra high end, there is sometimes a notion that "if it's made in a garage, it's better". The small up-and-comer has "new" concepts and ideas...then that same company, after they get big and actually HAVE some REAL engineering experience (and they start advdertising)is suddenly not tweaky enough and everything they make is "good but does not exhibit emotion" or some such goofiness.
If I sense that, some customers will admit it, some won't. It's like that in watch collecting too. Most serious collectors hate Rolex and dismiss them as commercial mass made watches. Truth is they work and don't break.
