Mojo ... give the guy some numbers ...
What do you think should be the cut off for those ... where it become just a spec and not audible ... (also many times there are trade offs being made to get a spec ... usually dictated by marketing ... who IMHO are mostly made up of brain dead zombies out to sell product to the unknowing public. My apologies to the marketeers out there.)

So is 0.01 THD much better then say 0.1 THD or even .3THD?? Do you think you can hear it? how about a S/N below 100db ...
