2008 7月-12月 第5項課程召集 - (5) CDPRO2 CD 轉盤製作班 (10月4日繼續組裝)

Hi Admin,

Just bank in deposit for CDPRO2M course. Please check.

BTW, I wanna reserve CDPRO2LF and large chassis if possible.

Please reserve the extreme version for me, sorry for my mistake.

I would prefer I2S implmentation to DAC that eliminate much jitter issue.

Does CD Pro2 挑碟的問題 mean cannot read normal CD occasionally?

Have a look at these links for which all the CDPRO2 modules seem most probably released from there instead of direct out from Philips.

Dear KK,

I have attended the open-day on 2 AUG and I had a thoughrough discussion with KK sir about my special interest in CDPRO2 project.

Since I have strong intention in making an integrated CD player using CDPRO2 (including digital in/out capability) rather than a pure transport. Personally I dislike SPDIF. I prefer the system clock being derived from DAC side, that should being known as least jitter.

I would use close distance I2S for data transmission between CDPRO2 and DAC, I2S also benefit to future expansion like DSP upsampling.

I express my vision in this project here and hope that KK sir can kindly support me on implementing my ambitous CD player.

After investigating the big chassis on open-day, I suspect whether this sexy metronorm a-like chassis have enough 實用面積 for my need. But anyway I still like to reserve this big chassis for this project.

Most modern DAC like BB, ADI, Crystal use same I2S bus so I don't think swapping DAC's is an issue. I have PCM63PK, PCM1702PK, PCM1792 right now. The very first is to craft the system architect, incorporating all the basic elements (transport, digital filter, clock system, DAC, LPF). This is really an extreme experimental project.

I wish to build a flexible system that the elements can be interchangable, like swapping DAC, digital filter, output stage. The goal is to build a CD player that is absolutely neutral and rich in information. And beat down my current CD player (Meridian G08).

I don't like tube output at the CD front-end. I prefer solid state that pertains all the information from source rather than round-off.

If I got all the datasheet of the IC's including CDPRO2 loader, this would help a lot in formulating feasibility of the whole system.

I may use PCM1702PK at the beginning. I got NPC5802 as well. I wish the CDPRO2 clock being fed from DAC side. But I don't have CDPRO2 data at this moment that is a constraint to me on system development.

I also worry the space in chassis. Or I need a more bigger chassis?

Dear KK,

I just bank in deposit for the DAC course and would like to reserve DAC1955 package. If not enough chassis space, seperate chassis is still Ok. But the clock channel between two chassis needs discussion.

Thank you very much indeed,

autumnleafcat.

等D人做好個DAC先...

KK sir,

Is it totally 32 pieces of 47uF/16V OS-CON?

I miss the 22u OS-CON (C62), 100R (R310).

KK sir,

Just finish soldering CDPRO2 PCB, missing 22uF (C62) and 100R at SPDIF output. But still OK for testing. How I can send you the PCB?

Have sent email to William. Board ready for test at any time.
