How hard can it be?

Unread post by Latteman »

How hard can it be to build a CD transport
I have a dac
I’m cdp less at the moment- using a ps3 optical out or a Sony Blu-ray coaxial
The sound is ok
I read an article where a guy pulled apart a Tibo cdp claiming it was a cheap dvd mech and output was driven off the hdmi - crudely -and added their own psu.
Would it be possible to attempt making a transport only- what would I need- a donor ?
How easy are they to disassemble and pick out the digital out signal
Cheers

Many years ago I did what you are suggesting.

I used a computer CD rom (could use a DVD version) in a small form factor PC case (with a power supply) and a chinese controller kit off Ebay, similar to this --------------

Took the SPDIF output to a DAC.

At the time my DAC was (by modern standards) not that good, so as a project it worked and made a reasonable noise.

Whether it was any better than using the digital output of a reasonable CD/DVD player is open to debate.

I've still got it somewhere, but only keep it for sentimental reasons ('cos I made it).

Thinking about it, there was a time when an NEC Multispin CD ROM reader, model CDR-602, was touted as being a very good CD transport.

It's a self contained unit and has L & R audio output and SPDIF output, via RCA phono sockets.

They use a caddy to hold the CD.

I know where there is one if you are interested.

Lots of YouTube watching has provided motivation and I’ve started a prototype chassis & hardware build as I await the controller from China

Also in the meantime I’ve picked up a used Linn Mimik cdp as it’s a compact size and has bnc digital out-
