USB > Optical > USB

PhantomGTR

好了，今次我點試呢，就由呢個 PC > Optical USB > Adaptor > Titan > USB cable > DAC 的聲音開始。雖然我套機同呢到很多師兄的機係小毛見大毛，但我相信我用緊既機，都係那作者的精心傑作，亦係我節衣縮食，冒著家變等等而成的，請各位看官不要見笑。

PC: i7 fanless PC built by Edison with his LPS
Software: Voyage MPD 0.10.0
DAC: Heavily Mod. LKS 002
Preamp: 田雨 TA 001 MKII
Power amp: Ediscreation EC -2
Speaker: Volent VL3

測試 combination:
A) Optical USB > Titan > USB cable
B) USB cable > Intona > USB cable (both USB cables are the same)
C) Titan > USB cable > Intona > USB cable
NB: Optical USB > Intona 係用吾到，detect 唔到。

結果:
1) C >> B > A;
2) 主要分別都係例牌想要既嘢，image, focus, stage, details, texture, fluency…… 簡單講，全面提升。令我最 impressive 的改進係密度同個流暢度，一切都很生動（我自己成日想套機係 準、真、live)，真係好大分別;
3) Intona 的音場後比 optical usb 的後一點同深多D;
4) C-B = (B-A) x 2

討論:
1) 如果未買 optical usb 的，買邊樣好？我覺得唔洗諗，intona，除非唔夠長;
2) 如果已經買咗 optical usb 的，過唔過檔好呢？經濟上可以既就轉會啦;
3) 如果用 Intona，一定要入埋 Titan。用 optical usb，都一定要入埋 Titan。

最後多謝當中各位毒害過我的師兄。

c hing, 個分別都明顯的，不用 AB 都聽得出，仲要方便好多呢。

Uptone regen 我無試過，Jitterbug我有幾隻。係我兩套唔同system 到，串聯 jitterbug 都係明顯會衰聲，但並聯咁插係機上附近的USB座，就有正面改善。如果插係貼住出 USB cable 的就效果最明顯。話雖如此，並聯時插邊到的分別很少。

In the test, I used a 30cm and a 50cm DIY silver usb cables.  They are the same except the length.

In my optical usb system, that usb cables play a very important role.  Different USB cables will get very different sonic performance in optical usb system.  Many c hings in this thread already experienced.

For the Intona, someone told me the difference of sonic performance between USB cables are not significant.  But I didn't compare in that test.

And the jitterbug, it's very bad in sonic performance in comparing to Titan.  Titan is very bad in sonic performance in comparing to optical usb system.  Optical USB system + Titan is very very powerful.  But Optical USB system + jitterbug worsens the whole picture of Optical USB system for sure.  I've tested many times since it's launched.

Intona前後駁唔同線都唔同聲，前後互換都唔同聲。

師兄，請問在你還有用這 intona 嗎？在你經驗，如果兩條 usb cables 有分別，將較好個條放前定放後會效果好D 呢？

一直在用。
我的情況是較好一條放在電腦去intona一段比較好。
