Just wondering what is the main difference between the two. Reason I ask is because after watching David Foster's Hit Man Concert on BluRay in 2ch Stereo, i was blown away in the SQ....for 2 hours I thought i was right there in front of the stage watching live. I have never experienced hearing the same SQ with an audio CD from my player or PC..... Even if i play an Audio CD in the same BR player, i don't experience the same SQ. So i'm guessing its the source media... Will SACDs sound like what i hear on BR audio tracks?

thanks!:D

    Likely a higher bit rate (word length) and sampling frequency (how many times the word is read). CD is 16/44.1 while your Blu Ray is likely 24/48 or 24/96. DVD Audio is as high as 24/192 and SACD is only a single bit rate (one word language) read at an insanely high sampling rate. My guess is that the SACD would sound better unless the BD is recorded at DTS-HD's max resolution of 24/192, which I believe is incredibly rare. The only disc I've come across is an old animation movie called Akira from Japan.

    Also, I lot more time is put into Blu-Ray audio getting the sounds just right. I've noticed this too. Blu-ray movie audio just blows me away with realism. I wanna say that in a music recording studio, they don't put as much time and money into finalizing the audio tracks as a Blu-ray studio.

    Another theory I have is that for some odd reason, the mind thinks that audio is better when there is a picture to go along with it. I've noticed in some movies, I'll hear a song and really get into it and be moved by the music. Then I listen to just the song (in lossless) and feel that there is something lacking. As odd as this may sound, I think there is an emotional aspect when audio is mixed with video just right that compared to listening to audio alone cannot usually recreate.

    Just a little of my psychoacoustic theory.
