@rblondeau I do recall some Cary CD 308 had SACD capabilities, some others had HDCD capabilities. By hooking up to an external DAC, you may be unable to play the high resolution layers of your SACDs or HDCDs as they typically require the use of the player’s internal DAC, or a DAC made by the same manufacturer as the spinner. So in short, you might get a great upgrade by moving to a Lampizator Amber 3, but it might not play all of your discs.
All regular CDs (redbook format) should play just fine.
