aint superior cd transport serves to supply superior data steam, 101% accurate?

If that is the case, then there is no denying,cd transport STREAM data with little correction from the onboard controller. A computer source (and future source that doesnt require a computer, i know they exists, but im unaware of them) is 102% accurate reading to that nano compared to micron of cd track since the data from the cd is read thru various ECC CRC etc..and to the matter of RF interference in cd transport, why is it a main concern when the data readout is digital? Microphonics from ceramic caps, what ppl shud be worried are the true EMI from the cd motor.

Or maybe i misunderstood, but from the DIY thingie on this thread, it seems like the transport serves data to external USB?

So what is a cd transport then?

Not really the USB, but the thingie serves digital data with accuracy to the DAC via coaxial/BNC.

Several people reported coaxial better than BNC and vice versa. it is sometimes confusing. I will just stick with BNC with the RG59. I think RG 6 is overkill ?

To connect USB to DAC it will need a converter. Common in the market is PCM 2702 + Xitel + a host of others. These solution dont offer good jitters.

Another way, the I2S, is a promissing tech but most dac dont have this.

not too long from now, there will be solution in this. and it is not costly. For the meantime, I just want to get this simple transport to run, to see if it is a real killer of CEC / ML or just another hype.

So, my clock, pcb supply board and caps are in.

I am ready to rock and roll this week.

Hows ur project?? Started?

besides, where did u find these items?? jalan Pasar??

Hi,

Please email Peter Deniel directly. He would be able to reply directly.

As for the rest, u need transformer, with 30VA 12-0-12. U can get the transformer at Jalan Pasar.

For RCA/BNC connection, I chose BNC because I think that is the lowest jitter.

With the above components, and mounting all those items on wooden board, it is ready to rock and roll.

So, how is it? Can rock n roll or not?

Well looks like the parts from peter will take some time to arrive. plus I will be attending to phase 2 of ZERO DAC mod. I hope to receive the parts by next week, if not, I will still tear apart the EZ31.

Ic. Thought that u oredi had the parts. I'm also gathering the parts now. Just waiting for the chassis quotation from jazzy939. Hope that it is affordable. Otherwise it will be a naked transport.

Hi

Thank you for the reply.

can I have the email of Peter Deniel, btw, which part u obtain from him??

For the rest, i can go down Jalan Pasar, its a bout 10 mins drive for me only. Or i may take monorail down to tiem square and walk across. heheheh

May I suggest u use some heavy ply wood from hardware house? or glue few pieces of mdf board together to create a very heavy base? or buy a good chop board from isetan supermarket, should be heavy n good enough, hehehe

just send him a PM. check the diyaudio thread.

also the items are better off purchased at the Pasar road.

ccschua: how much would the mod cost in total roughly? the output of the transport is Toslink or SPDIF? thanks

Guys, a question.
ringgit to ringgit if we were to compare this shigaclone and a CDROM transport kit, which would be 'best value for money'?
thanks in advance!

EZ 31 about RM 200.

mod items : RM 80

Transformer : RM 30

others....

I use BNC.

want to know more BNC, try google BNC, SPDIF and TOSLINK, in the acsending order of Jitters.

I think the cost would be less than 500 bucks for a complete working transport. Quite a worth of money as i read positive reviews from diyAudio.

ccschua: any chance that we could audition it when it's done?

very interesting project. make my hand itchy already..

any one still manage to get the ez-31? will go grab it this weekend..

chassis update.
materials choices would be either copper(from the pix) which can be expensive or aluminium, which is about 6-8 times cheaper.
Can't exactly get an exact quote as I do not have the proper dimensions but based on best estimates(based on the pix) it's around RM200, more or less.
I am also making an acrylic chassis for my own use but not for EZ31 transport, an alternative transport which I am currently experimenting. I'd say acrylic would be best 'value for money' in this application.

End of update

Does the rm200 comes wih copper or aluminium?

aluminium. copper is way too expensive...

But in terms of the quality you'd get using copper, it's worth the price right???

The copper might give a 'better' finish.. and looks expensive, right?
Aluminium is cheaper and easier to work with (softer). Once we have an aluminium prototype, then easier to work with other metals.
Right now without drawings and the EZ31 transport mechanism I can't even start. Anybody can give detailed pictures/drawing/dimensions

I just received the power board and the crystal. I am ready to mod this weekend. I will buy the wooden board at jusco , cost RM 6.50. and the power supply at pasar road, cost rm 30.
