most tweaks and cable claims are just plain marketing hype and a complete sham.
Unfortunately for everyone concerned.
Perhaps, just maybe, collectively audiophiles tend to get what they merit - lets face it, manufacturers are only around if they are sustainably successful! Making & selling beautiful luxurious "eye candy" with run-of-the-mill outsourced mass produced materials/parts is a solid sustainable business model for this industry. The high cost of beautiful cabinet work (exotic veneers) and stunning brushed metal face plates is highly appreciated by everyone, as is the value of precious metals such as Gold & Silver used in cables, as are monsterous technical hyperbole used to create the illusion of exclusive technology from what are largely off-the-shelf parts! High performance and costly but obscure aspects of the design (such as a short voice coil in a long magnetic gap) will only ever be appreciated by a small minority.
That's life! There is nothing shocking about this - it is just the reality of the high end audio market segmentation - no amount of crying or wailing will change this. Hardly anyone wants to plop $20K on a butt-ugly speaker because it happens to sound exceptionally good. It must first and foremost look damned good for that kind of money - sound will be a secondary consideration for most buyers even if they will never admit it (not even too themselves)!
