DIY CDPlayer "Audio Analogue - like"

[MacDLSA1970]

Hi everyone !

After building a pair of wonderful "TB-Needle" and assembling a little "Fenice20" amplifer, all with the same aesthetic, I am now building (better say "assembling", again ) a CDPlayer.
I'll use a PC CDROM mechanic, with its own +5/+12 psu and its "dedicated" (chinese) controller, a little "Fiio D3" DAC and a double 6n3P-i (russians) tube buffer, all thrown inside a alu+wood cabinet (aesthetic of course matched with amp & speakers).
My wish is to use the same CDRom used by Audio Analogue in their fabulous CDPs like the Rossini VT, the TEAC 5010A, but I could NOT find one "in the wild".
I want to say that here in Italy I found there's only ONE company that distributes it, but ONLY to "specialized companies"...
Then, no "private person" could get one from them (I already tried the "business friends" way, but it's really too complicated... ) , so I wonder if there's a way to buy this CDRom from other sources...
Does anyone knows anything about it ?

Maybe you can look also at CD-5020A or B? It's UART thou...
Try asking TEAC autorized distribuitors: TEAC AMERICA, INC. | Data Storage | Authorized Distributors

is there a difference between an regulair DVD-rom and this 5010A
becuase i have build also an diy cd-player and use the digital output connected
to an DAC. it works perfect. the only problem is that the digital output must be convert to COAX and that's not easy to do without any digital problems..

Pretty nice players... sure I'll contact all those US sellers (although I would pay the "regular" import taxes if I'll catch one !)

TTL-to-coaxial interface. Use a cable as short as you can...

[Jempie]

Does you mean the output for an dac, because I have try this and still hear some digital
sound even when the volume is zero.

I use now serial 100 nf to puls transformer 75 ohm to ground not ok ....
It seems it you must isolate the spdif ground ?

[MacDLSA1970]

Yep, it's the coaxial spdif for an external DAC.
If you hear some "digital noise" maybe it would be better to connect the CDROM chassis to the ground of your cdplayer case (remember all cdroms are basically made to be screwed to a computer case...)
After that, sorry, Jempie... I still do not have all the parts to complete my DIY CDp (I'm still waiting for the 220_+12V/+5V PSU) and test it all .
Only got some "webfriends" that did it and seems it works VERY well.

Inside the black heat shrink tubing there is that simple Cap+Res+Res circuit.

You will pay those no matter what. Unless Teac has a factory in EU
I don't know what reps are in EU, maybe try in UK?

[Jempie]

have try both ways connected to ground and not connected
still hear some digital sound.

it seems that isolate and not isolate will help, does anyne knows?

Could someone explain digital noise/, what frequency is it, as most (all) digital noise generaly found on digital circuits is way above 20kHz

Maybe the problem is NOT that little interface circuit ?
There could be several causes, so you can go "to trial"...
A> try to connect your CDROM to another DAC and see (hear) if the matter is solved
B> try to connect another CDROM
C> try to connect a CDplayer to your DAC

I am not so "smart" about digital noise(s), but with this words we can "summarize" MANY kind of "noises", typical of a digital disc player... like the clock(s) precision, wich seems to be the matter !
