From a designers perspective, it's handy to know what is going on in the MHz region even if it doesn't mean much to the lay person.You mean you rather confuse them with graphs that go to 5 Mhz, hoping they don't know better and buy your software. You have proven that over and over again.
WRT HQplayer software, you may want to consider that for most in the industry from a subjective, objective and sheer format conversion options POV, this software is nothing less than superb.
