CD Transport that has I2S hdmi output, cheaper the better.

It's the same OEM factory responsible for the Audiolab players if that helps with your research on the laser.  

Buy a brand new CD-transport, not second-hand, and it will last for many years.

Getting closer to maybe finding the NuPrime's laser, this Shanling uses the SAA7824HL that goes with it laser the Sanyo HD850

There might be a mix up with the Jay's Audio use of the Pro 2 laser assembly with the CDT2 Mk2. Since they stopped making it, Jay's now uses the Pro 4 laser assembly, despite what it states on their website.

Currently, the CDT3-MkII is the flagship, using remaining stock of the CDPro2 LF mechanics and an on-board Rubidium clock. Because Philips stopped production of the CDPro2 LF, the CDT2-MkII as built on their CDM4 mechanism [right] will be the model going forward. 

You can check it out on the 6moons.com review.

The more expensive CDT3 still uses the Pro 2 unit.

All the best,
