another OpAmps for tests: opa627AU+op42EJ. Someone said they are sounds heavenly.

師兄，你有無自己係 LKS 上試過同比較過？請問效果如何呢？

I understand only English. For china I use translate.google.com.
I intend to buy LKS Dual ES9018 in next month. Now only read articles about DIY mods for this DAC. Very interesting this one http://alchemist0.blogspot.hk/2013/11/ae86lks-es9018x2.html.
About OpAmps - you could read this thread on Russia http://forum.ixbt.com/print/0012/052174.html (use translate.google.com for translation). There compared OPA2132, OPA2604, LM4562NA, AD797AN,LME49990, OPA627BP and so on.

Ben,
我係用一粒49720 去取代兩粒49710 加轉接板，粒49720 直插嘅，冇加任何野。
用兩粒49710 時，用嘅板 ...

BTW, 你的 49720 放係 I/V 定係尾關？我放係 I/V。

I see.   In my understanding, HIFI components needs "mix and match".  Have Fun!

Hi,
I should type in English?
OK, I have installed the 49720 at the Back, just replace the 49710 without the adaptor.
But the big improvement which is the i2s cable, one C-hing said like doing something but without the condom
Cheers,
Ray

唉, 果條朋友幫我做, 要幾兜野($30?)嘅 i2s 線, 一插落去就 KO 條三幾千嘅 AQ Revan AES 72V 線, 頂 未煲都 KO 佢

煲好 49720 後會試, 再試埋 627 鐵殼

OMG, my friend DIY a cheap i2s cable for me, it KO my AQ Revan AES 72V digital cable instantly.

I will try to mix and match the opamp after the 49720 burn in, which including the metal case 627.

Cheers,
Ray

聽聞LKS可以較opamp電壓，blau sir是應該點做？

看完各位Ching嘅親身經歷及深入分析，真精彩！

hi ching,
are u using cat 7 lan cable for i2s connection? My CPT and LKS also have l2s input/output, just wondering if only use lan cable can connect the signal. tks!

我朋友用 cat 6, 遲啲會買 cat 7 再做條 i2s 線試

so, is it normal network lan cable only? I want to try the cheaper one first and go to buy cat7 later. tks

So envy u guys got I2S output device!!

Thanks, c hing.  Yet I don't have a reason strong enough to give up Voyage mpd system.

其實之前建立 CAS 都有想過 Voyage, DAC 決定用 LKS, 而面對電腦, 用我就識, Set up? 睇其它師兄介紹點 Set up Linux/Voyage, 對我似撞彩多過點 Set up, 明知自已力有不逮, 咁啱 QA660 出咗, 有遙控有板面顯示, 三千幾唔駛攪一駁好同入咭就得 仲聽講話 KO 好多 CD 盤咁, SD 咭又平, 自己影相又啱用, 再跟住有師兄話 QA660 用 i2s 去 LKS, $20K 嘅機都唔係佢果皮, 我就無力反抗啦

小弟未用過LKS，僅從以往經驗講下，各位ching指教。

其一、可以試下OPA2134，此爲專門for audio之OPAMP。

其二、IV用音樂味好的OPAMP，而Balance轉Single End就用速度快的OPAMP。以往小弟PCM1792 DAC如是，另Audiolab M-DAC的IV就用NE5532。

其三、换OPAMP，可以再睇下Feed back的電阻于並聨之電容，此處影响甚大。

其四、Balance轉Single End除用OPAMP外，亦可試下用牛，不过牛的FR要足够大，到70K Hz最好可以到100K Hz。好處係冇Feed Back，以及牛的初級電感大小亦影响音色。

其五、如Upgrade銀牛，不如同時upgrade埋 fuse同Power inlet。

其六、揀强國産串流機用I2S駁DAC，就揀可以外駁铷鐘的，而DAC入面的時鐘無需理會。

我也講一講，大多LKS用家；都加了一個鐘和換了電座了，而用單端的師兄們大多換了49710/20和Muses 02,我自己用平衡就只換49710,還有些將opamp電壓調高到13.5V,換銀牛的師兄應該也開始多。而BB2134應該不及627好。
