    師兄，呢條thread四年前有多啦！

用黎聽歌都冇話out唔out,就好次仲有好多人玩LP一樣,最重要就是啱聽啱用就得啦.

現在先嚟玩Shan Ling CD300...會唔會out咗呢.....?

Hi Chan Sir,

I'm new to the forum and i don't have XLR input on my Musical Fidelity integrated  amp. After reading this thread,  i'm interested in your hand made XLR to RCA Schumann Seriess cable at 1.0 m length.

regards,
Jasper
Melbourne, Australia

I compare the spec on the CD300 to the T-80 and the T80 actually has better spec ???
                               CD300            T-80
THD                         0.05%             0.003%
Dynamic Range        100db              115db
S/N ratio                  105db              115db

Does it mean that the T-80 is actually better and for less ??

I thought those are important numbers that dictate how a cdp sounds.

Any thoughts ?

You can use the schumann XLRtoRCA cable. It is the best and direct way. the cable body is come from US and solder the terminals in HK.If you want to try,just call me 94206363.It is free of charge for trail.
Mr Chan

Does anyone know if the RCA output does/does not utilize tube and OPA627 ? My pre-amp does not have xlr input so I am stuck with rca output only.
If XLR is indeed superior than RCA, I guess I can use the Cardas XLR-RCA adapter ?? Anyone use those and recommend it ? I prefer to keep signal as simple as possible (i.e no adapter in between)

Mr Chan:
Is your XLR-RCA interconnect a complete DIY ? It says Schumann series on the jacket ?

I am a newbie and I dont know how to type in Cantonese.

Hi everybody,
I didn't read everything but the PCM1794 looks like the PCM1792, same characteristics than in my Cayin CDT-17A.
So it is a real symetric scheme according to the specifications of the PCM. You have one PCM per channel. You have also from PCM to RCA output, for each channel:
- 4 X monochips AD847 I/V Section Op Amps.
- 2 X monochips Differential Section Op Amps: it looks like OPA627...
- 1 X monochip single-ended RCA Op Amp: to convert from XLR to RCA. I can't read but it looks like OPA627 as well.

NB:
Firstable, OPA637 can't be used in this CDP. OPA627BP are quite better than OPA627AP. Try to change AD847 by OPA627 in I/V section.
If you use only RCA output, take off the last (single-ended) OPA AND the RIGHT OPA of each channel on differential section (when you look at PCB from PCM to RCA output). So you keep only the Four OPA in I/V Section and the LEFT one on Differential Section. So you use only one "half-PCM", but you might be astonished...
If you use only XLR output, take off only the last OPA (single-ended) for each channel. You don't need them for output XLR. IMHO, the XLR (symetric) output should be much better than RCA output (asymetric=not symetric).
About the Tubes:
First hypothesis: each tube works for RCA OR XLR output: try to listen to the music without tube by RCA. If it works, then RCA doesn't need tube, and then tube is for XLR output. If it doesn't work with RCA but without tube, then the tube works for RCA output.
Second hypothesis: each tube works for both (RCA AND XLR) output. It means actually that half tube is used for RCA AND XLR output tube at the same time.
Actually, I think that tube works for XLR OR RCA output. So one kind of Output doesn't need the tube.
And to conclude, the best tube I have ever tried in my Cayin CDT-17A is Mullard E188CC "shield" BVA gold pins. But I have to try Siemens CCa "grey plates", RTC E188CC and AEG E88CC...
Here is a link of my tweaked Cayin CDT-17A:

NB2:
I tried discret AOP, superclock from Bursonaudio. They are far better than OPA627.



I hope that my reply will help you.

恭喜你又進一階!

我的CD300摩改後,音樂通透、悠揚、甜絲的感覺，陣陣滲出，沁人心扉。更不用說那離箱、音場定位的表現了。當然，這也有TELEFUND 6922的功勞。
Jensen銅管銅膜電容，配合膽機(TELEFUND 6922)，產生的威力，使我有：已有此機，夫复何求的感嘆!
套句陳煐光的俗語：可聽過世的機子。雖然夸張些，但從此覺得“一分錢一分貨”，不可儘信也。

這些不要太認真，大家都是找碗飯吃，不太過份咪得囉，我想到你家試試我的銀線在你套器材的表現，你有無興趣?

雖然不是D300的用家，但看到它的外形真的很是喜歡，只不知其聲音合不合自己口味，而對陳生的silver speaker cables小弟很感興趣，不知要多少米呢？可否給小弟機會試聽？

No problems!
Call me for confirm the time.

今早遇到難題(CD機原來燒了Fuse),好在陳先生的專業意見!唔該哂,6元一粒搞掂了!
想問下,係咪如果靚D那種$250(唔記得牌子)一粒真的會好點嗎?
幫助有幾大呢?
原來原庒跟機真係很差,只是五亳子一粒!(Fuse線身很幼和單薄)
現在期侍你的單支銀線!

真人俊D喎!

今期ＡＶ雜誌有位同好JACKY大贊HIFI FEVER和陳生的XLR>RCA

幫唔幫襯一回事，交流下意見，讓大家不要浪費金錢去撞，你幫我，我幫你，大家互相得益才是正確!
就我而言，CD300的627ap已OK，可以不換住，電容一定要換，換後出來的聲音好好多，非常大的增長。還有，自己考慮用膽部份聽歌仔多，還是用平衡部份多，cd300機內兩部份是完全獨立，可先改其中一部份先，容後慢慢改慢慢玩!

阿陳生真係唔該晒,我未有幫親都噤好對我....其實呢..我都好想摩下部機,不過我又想試下d最簡單既方法,換op同換線我諗係最簡單同直接既方法,因為之前我diy咗逝4395vf既dac落兩粒opa637bp,點知起震熱到不得了,結果都係換番627....所以,家下淨低兩粒637,都幾貴架...成日諗辦法用番..自己又唔識較增益...

其實阿陳生你覺得如果op同電容比較起嚟換邊樣會對音色既影響大d呢??

可否做xlr呢?幾多錢呢?

係喇!陳先生想問問部機既增益夠唔夠換opa637呢...因為之前整dac有對637bp淨,如果可以的話買多幾粒落落去,等佢去盡d.....

多謝陳先生噤快回覆,我都好有興趣不過今個月先買部機,無晒錢囉....下個月先有額haha..

陳先生的心機制作cd300絕對要推介!
用了一星期,曰夜播3小時,昨曰終於開始開聲了!我相信還可以進步,
條線xlr用料很好!嬴了我家中幾千元的線!
我的朋友在我家聽過後都目定口呆!

陳生條線好靚仔喎...我自己都diy左一條不過好樣衰...想問問係唔係要用75ohm線架...另你果條幾錢呀(細佬無乜錢玩貴野).....pm我呀....thx

你有無興趣這條線，正! call me 94206363
平有平玩，貴有貴玩，不過mod左平的，始終心思思，最後都要再mod，結果兩次加的錢還多，所以一次過儲足彈葯mod好的吧，少少心得!
