Sound improvement: The stage is wider and deeper and the instruments and voices have more body. The Bass seems more dynamic and precise and the high frequencies have a better resolution.
Upgrade your Player with the Supreme Clock1 +/- 1 ppm will upgrade the sound stage: deeper and wider and the sound will be less harsh and mor e silky.
The jitter of the 1 ppm Clock is 1/10 jitter of the normal clock of the CD-Pro.

 + power supply without transformer
Output stage with transformer
The actual transformers are tiny toriod's, inside an SMD package.
That eliminates the problem of a hum loop and makes the replacement easier!

Using the CD-Pro2LF module (VAU1254/31LF), you will get a high-performance CD-engine, which is designed to deliver an extremely good playability and very low mechanical playing noise.
The CD-Pro2LF (LF stands for "Lead Free") is the RoHS compliant version of the CD-Pro2M. From now on, all electronic products must indeed comply to the RoHS directive, so that they can be sold in the European Community, as well as in many other countries world-wide.
The CD-Pro2M itself was an improved version of the CD-Pro2 module which had been widely used in the high-end audio industry, like its predecessor, the CD-Pro module.
Compared to the CD-Pro module, the CD-Pro2M had indeed brought many improvements, like the capability to read CD-RW discs. Its playability had also been improved thanks to the recent CD10 servo-decoder and a new active filter switching for start-up and play. In these matters, the CD-Pro2LF shows the same performances as the CD-Pro2M module. Besides, its firmware has been specifically updated to allow playback of most of the current copy-protected discs.
The CD-Pro2LF module remains fully compatible with its predecessors, and it can directly replace the CD-Pro, CD-Pro2 or CD-Pro2M in your existing application. Indeed, it has the same dimensions and fixation points, as well as the same electrical connections as these modules. Last but not least, all these modules are based on the same standard DSA protocol for external communication, which means they are also software compatible.

The CD-Pro2LF is pin-to-pin compatible with the CDM12 Industrial standard.
The CD-Pro2LF show better performances, especially thanks to their improved error correction systems. Experience has also underlined that CD7 and CD10 are less sensitive to ESD.
The main modification of the CD-Pro2LF is the replacement of the laser unit, which has resulted in changing the flex assembly and the mounting frame as well. Of course, the new laser can still read CD-DA, CD-R and CD-RW recorded audio discs.
The Second modification was the replacement of
the TDA1305 D/A Converter, which was used with all previous modules by a new generation 24-bit 192kHz DAC : the AK4384 chip from AKM.
