CD-ROM Drives that Can Be Used as Standalone Players?
An anonymous reader asks: "I am using an older, standalone CD-ROM drive as my audio CD player in my sound system. It is a NEC 4X SCSI in a small case with power supply. The case outputs very clean analog audio, great headphone output and a SPDIF coax link which plugs directly into my receiver. It works great standalone, it has a complete front panel, ie backlit LCD display, stop, play, pause, next and previous track buttons. But it doesn't read CD-RW, it uses a caddy and it heats up the CDs quite a bit. I know that all recent CD-ROM drives have only the eject button, not all of them output SPDIF (and with DRM who knows what the future holds) and who knows if they will work with only the power connected? Which CD-ROM drives, old or new, support being used standalone, have a decent set of front panel controls (at least a play and a skip button) and output SPDIF?" Generally for this type of purpose, I'd use a regular old portable CD player, but these generally do not output to SPDIF, either. Has anyone managed to find decent examples of either piece of hardware?
How do you play a 16-bit PCM stream with a 1-bit DAC? It's not like SACD where you have a ~2.5MHz 1-bit stream. So what exactly does it mean to have a 1-bit DAC?
Additionally, there is absolutely NO reason to ever buy anything but the cheapest digital audio cable. Why? It's DIGITAL! If there's degradation of any kind, you'd hear it extremly well. There aren't multiple levels degredation. It's either total signal loss/corruption, or perfect signal. Just buy the cheapest cable you can find that works. Heck, for coax digital, even a cheap composite video cable would work. An audio cable might work, but it might not have enough bandwidth. A composite video signal needs about the same bandwidth as a digital audio signal. For optical cables, you'll want to find something that isn't going to snap if you drop it while you're installing it. There's a new method for making plastic optical conduits, that have a smaller minimum bend radius than the current cables.
