Something strange happened here…I did post an answer…it seemed to be there, and now is gone. I was telling Sherrif that’s up to him to prefer a juice 'made from fruit concentrate containing at least 8% of the real fruit" to a fresh squeezed juice, if he has the choice. But he should not criticize the guy that prefers the real juice, even if he takes the dog with him. In fact, probably you will not listen to the >22KHZ frequencies and Digital Audio CD is limited just to frequencies between 20 and 20KHZ…from there and taking out almost 80% you get MP3. The problem is that the higher frequencies are not just to call the dog, just ask your doctor and he will talk about a liquid that has micro bones in suspension, and about that some sounds that you can not ear but prepare this system for the change of frequencies and so on… You ask to a musician and maybe he will talk about transients, accords and other stuff that have an impact on the things you listen…even if only the dog can ear them. Ok, you listen to music using the computer, Ipod, or other device and it sounds great to you. It will sound good to me too, for sure. But feed the same stuff to a good system and you will see/listen the difference. Vinil 'died" for marketing reasons not for quality ones. CD was promising you heaven, even if it was not true. Now they sell you MP3 of the Microsoft similar and promised you CD quality, that it is not there. They try to dematerialize music, sell you files and use DRM to control the use you can make of it…they don’t care about quality, but business figures. Don’t be mislead, music files are a product, just a product with pros and cons, but when it comes to music you should not give up the exigency for quality, otherwise you will end up paying the same high price just for second tier goods.
