I picked this machine because it is very popular line of players, available in plenty of models, sizes, colors and variants. They share the famous interesting mechanism - "stable platter" which has a small turntable and plays CD's upside down. This  means that  the laser pickup hangs the optical side down hence does not pick up dust. CD is supported on it's whole surface and vibrates less.  When the platter stops, the CD does not get scratched like in typical drawers.  The massive turntable gives the user the feeling of solidity and confidence. Pretensions to high end even if far far away from VRDS mechanism of TEAC , Philips' CDM-PRO or Laserdisk, not to mention CEC TL-zero belt drive or Sony's heavyweight top loader spinner found in ES777 or SACD-1.

  A quick hookup of external testing lampizator to the pulseflow DAC chip (I wonder who makes these, I guess not Pioneer even if they have proprietary silk-screen) reveals the quality of these DACs. They have unbelievably detailed, rich and dynamic sound. One of the best bass I ever heard and plenty of goose bumps during even brief listening. Untill now I did not consider Pioneer any good in the sound quality department despite the sexy designs and cool mechanisms. But that's untill the Lampizator. Pioneer is one of the best bang for the buck. It can be had on ebay for next to nothing. The chip PD2028A / B sits in almost half of all Pioneers.
After hooking to the output legs (look them up on there is some residual hi freq noise present. You can filter this by connecting a 5nF caps to ground. This chip is symmetrical - balanced so you can make the player fully trully balanced by using all outputs from DAC and 4 tubes.
One warning - lasers and mechanisms of Pioneer are hard to get and pricey.

After hearing this setup the owner of Pioneer decided to go for internal but exposed lampizator. It does not look the best, but it just screams I AM A TUBED PLAYER.
