hifi audioI never really knew the difference between hifi audio and stereo. However there are some really big differences that you can hear in the sounds and the way that it emanates throughout, say your living room! I have a newer home theater system in my living room that is capable of hifi audio, I just never knew it. My brother, Douglas, was over watching the big game on Saturday with me this past weekend, and he looks at me and tells me that my home theater system is indeed capable of hifi audio. I looked at him and asked him to show me how to turn it on. Then after a few moments spent with the receiver, he was able to turn on the hifi audio. Everything sounded so much clearer, more pristine and nicer; more audible. I asked him why hifi audio was better, and he told me it is just a more capable and competent digital format. I am really happy because I never even knew my theater system had something as cool or as advanced as hifi audio.
