Yes, I have tried it, and it remains my main CD player. A simple marantz CD65 with tube output stage and some extra modifications. The sound is excellent.

I did something similar to my Philips CD650, a SRPP using a 6211, and I absolutely love it! Way better than my Sony CDP X555 ES & Audio Note DAC1..
At the moment I'm in the process of tweaking the I/V-resistor, might go for a 6N2P.

Maybe even better...
Sims real good (especially PSRR and CMRR noise rejection).
Don't know for sure in real life, never got around to building it.

Any squiggliues you see are only cause I'm simultaneously
throwing 5V of noise at both 120Hz and 400Hz at it...

using a valve circuit to replace the output opamps or even indeed his digi-lampizator using a valve to by pass the standard sp-dif output, both work very well indeed.

However ready made valve buffers and valve preamps work equally well once the signal is captured off the DAC as lampizators

I try it at my Marantz cd-48 using SRPP. In some music it sound great, open sound stage, full of music and airy.

But for some high pitching vocal , it turn to sound terrible.
Is it the gain is too much?

I Lampized a JVC cd player using a seperate 6SN7 preamp, and also rebuilt the case from wood and aluminum, with a clear plexi glass cover to see inside. It both sounds good and looks good and all I spent money on was for the solid Oak side panels and the plexi glass, everything else was salvaged parts and a NOS 6SN7 biased with Red LED's.

For me this is the best CD player I have heard yet, so I can't wait to finnish the Lampizator mod with the Philips CD670.

Such a great site!

I'm try to change it to Anode follower with 6n6p tubes.

It is ok to bypass the dac coupling cap from 47uf to os-con 220uf?

By "Lampizator" do you mean simply adding tube amplifiers after the D/A, or is this a specific circuit. I have not found anything by searching.

I've got some miniature 1AG4 power Pentodes that would be sweet due to their size, but the plate curves don't look that wonderful. One would have to run a really steep load-line at 41V on the plate unless I biased it at -4v on the grid with 1.8mA of anode current, if I interpret this data correctly I get a 2583 load line:

NJ7P Tube Database Search

Since the typical CD Rom Drive only uses +5 and +12, I would need to add a B+ supply (Flyback) to get 41V for the plate and screen.

Neat tube, but linearity doesn't look that great.
