I listen to all my music through my computer. I own Diva Swan M200 studio monitors and a Sound Blaster Audigy. I am thinking of getting an M-Audio Delta Audiophile 2496 so I can Listen to DVD-A's and SACD's on my computer and so I don't have to use that shitty Radio Shack 2-RCA to 1/8" Stereo mini jack converter which probably kills some signal (right?) Is there a reasonable (audible) difference between CD, DVD-A, and SACD on my setup and in general? I'n not concerned with DTS 5.1 just stereo. Can PC DVD/CD-ROMS play SACD's? Is there a significant difference between 24-bit 96KHz and 24Bit 192KHz?
