If I don't need the remote control and other fancy control / display stuff, just play, eject and stop button, what do I need to DIY a sound CD transport (top or front load). What circuits would I need? Where can I get the CD drive and schematics?Presumably an over-engineered separate power supply and casing are envisaged.
Thank you.

One of the best transports you can buy is the CD-pro2

Get yourself a CD-Rom machine with digital audio out. This will plug right into an external DAC and works amazingly well stand-alone.I started with the recommendation of EdM in last month's Positive Feedback and bought an old NEC CD-601. It sounds great but I wanted something a bit more user friendly so I got myself a Creative Labs 52x CD-Rom deck with remote control for $20. Digital audio out goes into my Scott Nixon DacKit. I'm working on just what you suggest: nice wood box, beefy power supplies, and adding a display of track number and play time based on my own design, taking the Q subcode info from an Analog Devices digital receiver and processing the register info through a small PIC processor to an LCD display.
So far all i can say is that even with wires hanging out all over the place this is the best CD audio I have heard...at least in my setup.

I'm very interested in adding the display, please keep me updated. I'm also using the same Scott Nixon DAC. I bought 2 of the creative drives, one for my PC and the other I have disassembled to use as a stand alone transport. I am planning to build the transport in the Sakura Flatfish style. I've been too busy recently to finish the project, I have all of the parts except for the wood "plinth" which I plan to mill out of hardwood.
Hi,I am looking to do something similar with a CD-ROM too. While searching the net, I found a taiwanese site selling a ready to go display unit for the CD-ROM. Take a look (unfortunately, only in Mandarin but there are pictures).

Wonderful!!!CD-ROM usually comes with 4X, 10X etc...how are these spec comes into the selection criteria? the lower the better or the faster the better? how about DVD drive?
PC CD-ROM used 4-prong molex providing +12V and -5V(?). Do the CD-ROM used both rails or either one? AT power supply may be too noisy for audio purpose...
In general is the quality of PC CD-ROM superior or inferior when compared with the drive inside a CD player? I suspect computer grade is a bit more demanding than audio grade...
The CD-Rom needs both 5V and 12V. The case of the 52X says the requirement is 1.6A for each but if I remember right it's more like 1.2A at 5V and 200mA for the 12V.Doesn't an audio run at 1x no matter what the max rating of the drive?
And BTW: the Creative 52X is very quiet.
cheers

It's going to be the external DAC and the clock it references that determines the sound quality. My impression, perhasps false is that CD-ROM units are sometimes a bit noisy mechanically so you may want to watch for that. If I were doing this I would build my own regulated audiophile type power supply. The switching supplies that are used with PC's are switching supplies and noted for putting out RF.
Yeh...ARAIK...lower speed CD-ROM's are less noisy...IIRC the clock a DAC refers to is inside the CD-ROM?
