Hi Komigenie,

May be not build, but re-build, yes! Have a look at the Philips CD104 tweaks, thread.

Cheers,

Richard

Komigenie,

That is what I did, there were gains in detail and soundstage. Also have a look at the shingaclone thread:
Finally, an affordable CD Transport: the Shigaclone story
There is a lot of evidence to suggest that structural mods to the transport make a big difference.

Cheers,

Richard

No. That PC board / module is an interface for a computer CD-ROM drive. A CDROM drive already has all the control & servo systems build into it (hence the name IDE = Integrated Drive Electronics), it isn't JUST a transport.

The CDM0/1 require external servo systems, data separator etc.

Yes, certainly you can use another servo board, but it has to be a servo system compatible with (1) radial tracking, and (2) single beam optics.
The chipset made by Philips for those radial tracking mechanisms does all the hard work, so any board incorporating say the TDA5709 and TDA5708 should work. BUT, those chips just implement the servo sub-system. You need a microcontroller to oversee the whole thing, which may not be part of the servo board, depending on where you acquire that servo board.

Most 'controllers' and kits advertised on the www are not really controllers at al, they are simply interfaces that support the universal ATA instruction set to an IDE (also known as parallel-ATA) CD drive. Those types of 'controllers' will not work with the CDM transports.

CD-Pro2LF

The CDPRO2 is certainly a very nice module, and easy to use. Plus it will read a lot of disc formats that the older optics won't recognise.
