請問 DAC 原理和製作班的TDA1451A 是否用不到 44.1kHz 以上的 Sample Rate 呢? 如果可以我都想砌埋這部 Transport。
作者: kk_ho    時間: 2008-2-22 16:35

We have DIP-Switch setting for this.

Available mode
44.1KHz, 48KHz, 96KHz, 176.4KHz, 192KHz
16bit, 18bit, 20bit, 24bit.

CDM-9 is better than CD pro 2?  but i see many hi-end transport use CD pro 2... :roll:
作者: kk_ho    時間: 2008-2-24 16:31
We have both CDPRO2,CDM9, 3, 4, 12 on hand for written the SW.

Also, up-sampling function will available.

Our CD transport course 需要銲錫電子零件, DIY ma....

Not a simple Plug and Play course

Alot of theory and up-sampling theory(FFT, Z-Transform) will be teach.

Does this mean diy a CD player??
作者: kk_ho    時間: 2008-2-25 11:33
YES.

1. The CDM-X loader is pre-assemble, not recommend for Diyer begineer to assemble it, include the SERVO board, alot of testing needed by equipment after finishing.

2. Power supply board + Digital output board + Up-sampling are in same PCB. Diyer are need to assemble this board by using difference kind of compoennts.

3. Front panel : VFD and LCD are available by adding display off function to get the better sound quality.

4. There are 2 kind of chassics is available.

PS : The upsampling function is selling together with the power supply board and will not sold seperately. Which adding alot of extra function with the MCU.

Thks KK.  I'm a newbie in DIY and just started to register some courses at here.  Only have some soldering skills on electronic toys many years ago (when I was young... :-))   Will this DIY course too complicate for a beginner like me?
作者: kk_ho    時間: 2008-2-25 16:39
Leon,

It should be OK for you.

For this course, student who need to solder a QFP package IC (Up-sampling IC) on PCB.

For normal compoennts such as R,C,L, we have teacher will teach you. Sure you need to learn some basic skill (will provided in the course) to learn the colour code, the direction of diodies & capacitors.

Also, you need to learn and do how to make a floor planning and assemble the metal case, you need to drill some of the holes.

PS : Our course is not a plug and play.
It is a real DIY course.

Can we have an idea on the price ranges of the standard and hi-end version first?
作者: leonlau    時間: 2008-2-25 23:28
Just 3 more questions:

1) Can it be made as a top-loading one?
2) I only have a Li-Te DAC-AH DAC.  Can it be used with this CD transport?  Or, those in the DAC course are much better combination with this one?
3) How does it compare with Shanling's CD300?

Many thks,
Leon

作者: kk_ho    時間: 2008-2-26 00:04
Leon,

I will promise you to keep one seat for you.

We will planning FULL course for
CD theory(with mod) + Transport + Up-sampling + DAC + Tube output.

5 course together.

Ans your question below:
1. It is top load plus. (Secret)
2. 終極版可選True16/24 bits out, 44.1Khz, 48kHz, 96kHz, 176.4kHz & 192KHz output , 用家可用這高階輸出接至閣下已有的192khZ的 DAC 如 AV Amp, Wadia etc. 很多用家封印了具192khZ 的解碼能力多時
3. I don't have CD300.

作者: kk_ho    時間: 2008-3-10 23:48
Yes, it is equip with this.

We have upgrade daugther board for 7x4 config.

32KHz, 44.1KHz,48KHz, 88.2KHz, 96KHz, 172.4KHz, 192KHz
16bit, 18bit,20bit,24bit.

2 differential IIS or 2 invididual IIS, 3 X SPDIF out, output at same time.

5 input : IIS, IIS, SPDIF x 3

It is not a simple Plug'n play toys.

Decode two difference IIS and output in matrix mode.

Decode the IIS signal and output the differential IIS signal to 2 IIS port.
Diyer simple connect 2 DAC to form a 4X DAC mode. (48bit resoluton / channel)

作者: leonlau    時間: 2008-3-22 02:11
Hi KK Sir,

Thanks for the demo session arranged today.  Pls reserve me a seat for the CDM-9.  For the other upgrade items such as LCD panel, LED light, cap, plugs, ..., do we need to confirm them now or can we confirm them at the 1st session (just don't know whether you need to order these non-default items beforehand)?

Moreover, I'll be out of town during Apr 15-30.  Best if the course can be started after this period.

As I'm a DIY newbie, it'll be too intensive for me to construct the pre-amp + power amp + CD transport all in a short period.  So I decide to cancel my reservation in the power amp course and focus on this one first.  This can help me to get more time to run in the toys one by one each time in order to experience the differences.

Many thks,
Leon

K SIR
作者: leonlau    時間: 2008-3-24 01:39
The demo uses the same MCU/digital output/reclock/power supply boards, only the differences are the loader and stabilizers (KK, pls correct me if I'm wrong).

1) CDM-9 + downgraded stabilizer: can only locate the vocal voice, difficult to position other instruments
2) CDPro-2 + default stabilizer: overall resolution improved comparing with 1).  However, the vocal voice is weak.
3) CDM-9 + default stabliizer: compared with 1), the resolution had been improved quite a lot.  Positioning of both vocal and instruments clearly.

As only vocal music is tested using the 3 setups, personally, I prefer 3) if compared with 1) and 2) directly.

As the kit can allow us to interchange CDM-9 and CDPro-2 with little changes and no need to change other sub-systems, I think this can provide us some flexibilities to adjust or fine-tune our own music listening experience when we use this CD transport to fit into our own hifi system at a later stage.

Leon
作者: leonlau    時間: 2008-3-24 01:54
KK, I have a crazy thought.  Is it technically feasible to implement both CD loaders with the other sub-systems in a box by adding a switching mechanism to switch all the signal/power cables from CDM-9 to/from CDPro-2 (just like to have a double CD loader player) without affecting the sound base?  Of course, we can use only 1 loader each time.  If this is possible, we can use the strength of each loader to listen to different kind of music just in 1 box!

Am I too crazy!?  I'm absolute green on electronic area and only think from an user's point of view.

Leon,

See my comment below:

1. At the show, we are using RV01 power supply board, it is a basic one. (for our course, we use RX03 power supply board, it adding a lot of feature, not disclose here la....)

2. RX03 can be adding Up-sampling board at future time. There are 2 version of up-sampling board. Basic and Advance
Basic : 4 output mode :
44.1/16 DSP re-clocked + Interpolation (not traditional TCXO clocked method.
44.1/24 DSP re-clock + interpolation,
96/24 DSP re-clock + interpolation,
192/24 DSP re-clock + interpolation

3. TWIN loader. (We can support !!!)


We have DSP engine, other does not have...... just stay on plug'n play level.

作者: hcheung    時間: 2008-3-29 23:57
Dear KK,

既然你話人"BS",我又大膽糾正你老哥的錯誤,以免誤人子弟.

Case 1
"You are need to study more"
1. "are"之後應該用過去式(past tense),應該是"needed".
2. 但在這裏"You are needed..."變成passive voice,文法上不正確,這句子應為:"You need to study more"

Case 2
日本群馬縣是沒有秋明山的.只有一個榛名山.
秋明山只是漫畫家虛構的地方.但榛名山真的是有很多髮夾彎...

Admin,

Sorry, it is very difficult to me to be free on Sunday and Holiday. I have to celebrate Mother Day with my family on 12/05/08 and I have to go to Church every Sunday. Do you have any other option?
