IMHO, in high-end investing in a good quality and trained sales network is much more important than just advertising in magazines and websites. Most of the times if a good dealer knows of a product before the webpage announces it, he has an opportunity to approach his customers with novelties and attract their attention and purchases. Also, as he knows his customers, he is able to organize his sales strategy in a staggered way.
Most curious people (like me !) always know where to get their first hand information - google advanced search can be very efficient!
Sometimes I feel people over-valuate manufacturer websites in high-end - in general direct contact with dealers and distributors has been much more efficient for me, as well as participating in audio forums such as WBF.
