This is absolutely a beautiful con - and I believe it's absolutely legal, regardless of the fact that it's pretty unethical......
Now, I would not buy into any of that crap - nor would anyone else with more brains than money - however this is a case of beauty being in the eye of the beholder...
They make no measurable claims..... it's all esoteric crap that cannot be quantified.....
For example - when speaking of the RR-77 the writer stated:
The sonic artifacts of the recording process (such as soundspace, soundstaging, imaging, detail recovery, and so forth) all had a dollop of naturalness applied to them so that they enhanced the musical content of recordings (like timbre, beat, meter, tempo, tonality, and harmony) so that the Hi-Fi musical experience was more like a live musical experience.
How would one go about quantifying something like "a dollop"?
What measurement would you take into a court of law to prove that the dollop did not exist?
This (especially) since the seller could come up with every customer who was either too stupid to know the difference - or too embarrassed to admit they were stupid enough to purchase this crap - to say that they did get that "dollop" of difference in their rooms.
In fact - adding things in the chain can change measurable artifacts of the sound - but measurable changes can not be defined as to being "more pleasing" or "less pleasing" - simply different - which means it is a matter of perception - not anything concrete.
Personally - I believe that anyone stupid enough to make these purchases (and there must be people spending the cash or this place would be out of business) truly deserves to be parted from their money......
I don't feel sorry for these people much the same as I don't feel sorry for people who get conned out of their hard earned cash by buying into scams where they send a pile of money off to someone who says they won a lottery they never played - or the scams where they get an email saying someone died and we want to send their millions of dollars to you with the understanding that we'll split the cash - and any other scam that should be quite apparent to be a scam.
Even though in those latter cases I mentioned it is illegal - I still don't feel sorry for them.
Stupid people do not deserve my sympathy....... my pity perhaps - my wild laughter for sure - but never my sympathy.
That might sound cold and hard - but IMHO people deserve what they get when they willingly part with their money by being stupid - which is not the same as someone breaking into their home and stealing their belongings - or knocking them over the head and taking their wallets.
