Frankly, if I don't trust their marketing, then I don't trust the company.
Ha! That includes most cable companies, and might as well lump in all the other marketing BS we get bombarded with in the media.
You know when you are dealing with a BS company....
...when you read statements like this:
"You can expect a 15% to 20% improvement in sound for each level as you move up the line. The improvements are in soundstage, resolution, realism, musical presentation, impact, etc."
Me: yeah, the humidity in my room changed from 44 to 45% yesterday, and I immidiately noticed that the realism dropped by 3.4%, yet the musical presentation actually WENT UP by 8.3%. I was able to compensate by turning the lights on in the kitchen and changed my socks. Puh, that was close.
