The problem about Hi-Def audio is the “producer studios/companies” want to dematerialize music sales and to sell compressed files (reduced size facilitates sales) with a quality the average buyer consider as “CD quality” and is reproduced via equipment that would not “show” the advantages of a real Hi-Fi sound quality. SACD was supposed to meet these parameters while DVD-Audio was using a dif method of recording that would not keep the all sound wave, so it could explore present surround sys that try to pass the idea that the “glamour” of surround sound = Hi-Fi at its best and that may be not true. Sometimes surround is far from ideal, as it doesn’t reproduce the normal way you listen to live music, where you will no sit at the “mid” of the players, for sure.
