Default My new CD-Shuttle!

Hi to everybody in this amazing forum!

I’m very proud to present to the diyAudio community my last work and to share my big joy!!!

I passed last (many!!) months designing and building a complex CD player based on an excellent (tweaked) Philips CD-PRO2M module.
It looks like a NASA Shuttle – really high tech!!

Since the silk-screen printing still miss I am thinking about a name for it ...maybe CD-Shuttle (not really original but funny)!!
...hints are welcome!!

I bought only the three big feet and the cd clamper from a skilled turner!

Everything else is Hand Made with common tools and a jig router with fine regulation.

I adopted different solutions to fight the mechanical vibrations: the CD-PRO2M module is fixed to a thick machined dark plexiglass support, which is fluctuating through four couples of opposed little magnets; the case is made of two wonderful dark pieces of dampen acrylic and 8mm anodized aluminum; everything lean on three large aluminum feet filled of a sandwich of damping materials (sand, cork, soft rubber, closed cell rubber and a soft ball).

Ah, also the aluminum finishing is made by a craftsman... I didn't want to deal with dangerous sulfuric acid tanks!!

Absolutely exceptional work! You're making me envious.... Anyway, I suggest a name that expresses the build quality and insensitivity to vibrations of your CDP. You know, something brutal like "behemoth" or "titan". Or you could go the other way and call it something like "CDP Mark One" or so, because it's the mother of all CD players! My two cents...Again, superb work!

Thank you Madscience!

I have annotated your suggestions

Your name suggests me you are crazy enough to start a similar project! You only need AutoCAD, OrCAD, some tools and tons.. tons.. tons of patience!


Here is the pulsating heart of the Player, a very good TentLabs XO

Guido, look what a special treatment I reserve to your precious module!

Thanx!!!

I love DIY! So no problem if someone copy my design!
I'd like to see other players like this!


It's up to you "Gear Builders"!!!

For those who are interested I can even send the CAD drawings.

I like your attitude! Screw the big industry with their copyrights...That's why I love DIY.
Right now, I'm still focused on speaker building after having completed various gear (pre amp, power amp, sub amp, sub, fullrange speakers). My CDP is very good, it's a Philips CD880. I found it for very, very cheap. .
By the way: What DAC are you using and what kind of output stage did you use?

ps: My metalworking skills are limited, but still, I'm proud of my power amp:

Hi madscience

your amp is very goodlooking. I would have used some biggest and solid panels (at least for the front panel) ...but I know it's not easy to find thick aluminum!
I'm lucky to live close to some shipyards and you know, yatchs are made with every sort of exotic material (who can buy such thing can afford exotic materials!)

Maybe in the future I'll make an amplifier too ...I'm thinking to use monoblock vertical configuration, like M. Levinson one. Do tou like it?

The analog out of my player is a kind of "service output" so it's connected to the onboard akm dac (it has to arrive a diy dac, I already started the design!!)
More attention I give to the digital section of the circuit: a TentLabs XO directly feed the CD-PRO2M and the S/pdif reclocking section (D-Flip-Flop).
The digital connectors there are: XLR 110ohm, BNC 75ohm and RCA.
The player is extensively shielded: a copper foil underneath the main board, two copper boxes shield the delicate digital circuits and the noisy display and controller board.

Give a look to the magnetical suspension:
