繼 Audio Note 和 Pass 之後，47 Lab 不愧是這十年來帶給音響 DIY 社群最多創意和活力的音響製造商。從 Gainclone 擴大機和 NOS TDA1543 DAC 為濫觴，後來又推進到類比領域，Phonoclone 儼然是當今 DIY 界 C/P 值最高，表現極佳的唱頭放大器。如今在 CD-Pro 2 風潮泡滅之後，47 Lab 的信樂燒系列 Shigaraki CD-Transport 又成為新的 clone 流行，觸及到 CD 轉盤這個較少人 DIY 的領域。

Shigaclone 最早從波蘭的音響討論區 www.audiostereo.pl 肇始。有人拆解 47 Lab 原廠的 Shigaraki CD-Transport，發現內部的機構和伺服模組，與便宜的 JVC RC-EZ31 手提音響雷同。於是有人開始去買 JVC 的手提音響，取出內部機構，配合高品質的電源和穩固的機座，結果得到不錯的表現。後來，加拿大 DIY 名人 Peter Daniel 又將這個資訊引薦到英語世界，在 diyAudio 引領熱烈的討論。

Peter Daniel 不愧是手藝精湛，非常有行動力的玩家。從去年三月到現在，短短一年間，他已經測試了許多種電源架構和機體結構，讓他的 Shigaclone 日益成熟。直到現在，他聲稱他的 Shigaclone 表現非常優異，不但超越了他研究多年的 CD-Pro 2 轉盤，還成為他的 reference 轉盤。

我過去一年密切地觀察 Peter 的進展，如今看來，去年年底的組態已經相當成熟了。從照片看起來，真是相當精緻，架構卻又是那麼地簡單。

JVC RC-EZ31 簡單廉價的 CD 讀取架構，理論上不會比 Philip CD-Pro 2 好。但正因為簡單，容易使用，所以對於技術能力不高，儀器設備不足的 DIYer 來說，反而比 CD-Pro 2 更容易做出好的結果。這也和 non-oversampling TDA1543 很容易就有好聲是相同的道理。

總之，玩 Shigaclone 比 CD-Pro 2 便宜多了，卻似乎更有趣，更好玩。我也很想買台 JVC RC-EZ31 來試試看，但國內似乎沒有進這個 model。卻不知道國內有沒有其他手提音響使用了相同的讀取機構呢？

Hi dominique,

Do you know if I2S output is available?

呢篇文以前都睇過~見到好多外國FOURM都走去買部JVC返黎拆

Hi CKL2,

There is no I2S output in original 47 lab design.

The 47 lab's design is to pair to NOS (non over-sampling) DAC; i.e. no I2S output is required.

No sure if DIYer can add the IS2 interface through PCB's LC78601 or LC78622.

Regards,

Dominique

好多外國FOURM都走去買部JVC返黎拆....can find it from China SHZ?

Most people would agree I2S is better than SPDIF. People learned how to tag I2S from CD-Pro2. :)

Hi CKL2,

Do agree that IS2 has its' benefit while IS2 specification can only support a very short distance.

I have modified my Logitech SqueezeBox with IS2 support. It is a very intersting project but not many DAC support IS2.

The current 2 DAC I am using already cannot support IS2; Weiss DAC2 & 47 Lab Gemini.

Let me know if you interest on my Logitech SqueezeBox with IS2 support .... :-)

Yes, the major concern of I2S is the short distance. I don't have an I2S DAC as well. You are an experienced DIYer.

Hi CKL2,

I am just a Music lover, cannot afford much time on DIY.

I used to my Logitech SqueezeBox to a Clock correction device through I2S and then connect to a DAC through SPDIF.

Make a great improvement on SqueezeBox performance.

HiFi .......just a joke ....

As a 47 lab lover, I will say it is an art to use such cheap components to achieve such sonic result ...... :-)

Dears,

I am the blogger of this article.
Finally, I have built my own Shigaclone last month.
The unit is cheap and sound is surprisingly impressive.
The DIY details and more photos are published in another post:

Shigaclone is absolutely worth to try.

47 lab在香港唔流行
可惜

Any update of the blogger's cloning exercise(s) ?

I actually have a Shigaraki CD transport and am happy with its sound. It is not expensive. 10 years ago it was priced below $20K.

Yes, the Shigaraki is a relatively simple and basic CD transport. Its remote control offers very limited control functions. No direct access to a track and one has to forward one by one to a track. From this perspective, $20K is not cheap. But from the pure music, it is well worth the money!

嘩記得兩年幾錢幫朋友買一部47 lab, 唔記得咗咩型號嘅前級, test 咗幾個鐘頭, 印象深刻, not bad

小！又係福頭丁滿！
一有人支持就狂推舊貼！
收皮啦死丁滿！
小你 有本事就自己出貼啦！

Haha 大部分情況之下都冇留意到 old dead or active

只係睇嘅主題有冇趣, 真係佩服Moon, 佢應該有幾個身份, 唔知佢有冇一個身份 係正常同人 交流吹水

行為固然有點點唔coom, 但係有可能動機善良, 有冇咩破壞力
