I use the same one as you, too bright for my system. and hard to make directional cable too.作者: samuelsum 時間: 2008-10-14 09:26
AQ好o野來...買廠線有二手價值, 但我買廠會買二手
主要搵好特別既, 例如絕版日立6n的訊號線, 但spk線未曾在二手市場見過 (日本都未)
我都有diy AQ, 都幾抵玩, 本來只抱一試無妨的心態
用緊2x蚊一尺的, 要注意自己造線時, 要用返廠方suggest的長度 (有部份廠唔會講, AQ就係其中一個, 是一位朋友可以直接响美國問返來的)
AQ / canare = multiple of 1m
belden 應是multiple of 3尺
加埋canare 75ohm頭, 再買個cheap鉗200內
總計: (25x4) + (35x2) + 200 = 370 (應該平過依個數)
點解唔去試下 :?: 平價又好聲的diy digital cable, 可考慮canare / belden...唔記得咩價...去鴨記華x 睇下, 佢有個平鉗賣作者: accphoto 時間: 2008-10-14 12:54
如果是 DIY Digital 線, 我會 suggest 用 Canare 75ohms + Canare 頭,300-400元 攪點,效果唔會俾呢的線差。如果唔係就買的貴的 Digital 線。作者: alfcat 時間: 2008-10-14 16:12
For coaxial, I have tried Canare 75 Ohms as well. Very nice at that price. However, I can't find Canare plugs.
For RCA 過機線, I am using Audio Quest King Cobra DIY. If you don't use the battery, it won't sound too good. If you charge it up with a 72V battery for >12 hours, you can for sure hear the difference.
Sam_Sam師兄提到的$200cheap cheap鉗仔,我聽講過canare插頭是六角形(安裝線心的部分),所以最好是用回原廠的鉗(六角形,剛好可以fit到)唔知係米真呢?如果要買原廠鉗,又在哪裡有售? 幾多錢?作者: williechu 時間: 2008-10-14 19:19

我在圖書館的音響雜誌裡看過Audio Quest線,我都知佢唔簡單(知D唔知Dla~),都好想整返條玩吓,請問在哪裡可以買到Audio Quest King Cobra ,那battery是不是在原廠銀上那枚長方形的東西?又在那裡有售呢?大概幾多錢?還有線身又要多長才合廠方標準?作者: kk_ho 時間: 2008-10-14 20:31
Asking my friend Small Chan, comment below:
Total $ of the cable should be 15% of your total $ of your equipment.
If your system is 50,000 (Speaker + Amp + CD)
Your speaker cable + power cord (amp, CD), + signal cable should be around $7,500.
It is for non-Diy figure.
Assume compoennts cost is around 1/3 of end sell price.
Say, you should use $2,500 for those cable if you need DIY.
Exceed this limit, the difference is not too large due to the limitation on your system.作者: williechu 時間: 2008-10-14 21:01

O~ 明白晒.如果這樣計算,當我diy線材時,線材價值應該大概是system的5-15%就足夠la.作者: autumnleaf 時間: 2008-10-14 22:07
In my experience, good cables convey 100% performance of your equipments, regardless of your equipment cost. I used to brought my cables to my friend's home to play around. The result told me even the amp is cheaper than the cable itself, the amp still shine through. You know better your amp characteristics with decent cables ...
List of equipments and cables on that day:
My friend's owned cables:
Taralab The One interconnect (D/A->pre),
NBS (forgot the model) power cord (D/A).
Zu Mother II power cord X 2 (pre and transport)
(forgot the model of digital cable)
XLO (forgot the model) power cord (*)
DIY green Cello interconnect (*)
Kimber cable (forgot the model) interconnect (*)
AudioQuest Midnight Blue speaker cable Bi-wire (*)
(* = replaced from the system)
Cables I brought:
Stage III Concept monument 1.5m interconnect (preamp -> power amp)
Audioquest Volcano DBS (speaker cable)
Analysis Plus Silver Oval Interconnect 1.5m (*)
(* = tested but not use)
My friend's equipments:
PS Audio Lamda transport
PS Audio UltraLink D/A
Audio Research LS7 preamp (mod to have IEC power socket)
Audio Research VT-60 KT88 X 4 50W X 2 (use original power cord)
ProAc Tablette 2000 signature
Foundation Designer stand
Solid steel series 5 rack
My friend had never upgraded his system for more than 10 years because his system was thouroughly break-in and gives stunning bass from the small book-shelf speaker that I cannot believe . However, meanwhile, he had upgraded his cables several times. Because his system is quite sensitive to show off the sound improvement on replacing cables. Even some cables cost as much as his Audio Research LS7 preamp. He uses cables to fine-tuned his desired taste.作者: alfcat 時間: 2008-10-14 22:12
Willie,
King Cobra can be found at 永盛 in Sham Shui Po.
舊電是我自己整的, ha..ha.. 72V. 你可以好容易在鴨記買到12V 一粒的電, 好細的, GP 出. 6 粒合埋就72 V. 也可以用 48V, 自己 choose.
King Cobra 內有4條線. 無記錯透明那條是 Signal 用. 有方向之分.

充電池?米又要買個充電器? 另外,條電配咩頭好呢? 這樣製線,大約要幾錢呢?仲有電池同條線之間如何聯系呢?作者: williechu 時間: 2008-10-15 00:07

No, the battery is Lithium 12V each. No need to recharge. The battery pack can last for over 2 years.
See this thread of mine in creating the battery:

Second thread I posted on the arrangement:
http://www.hififever.com/forum/viewtopic.php?t=1812&highlight=%E8%9B%87
As I have said there are FOUR wires inside the King Cobra. Use the Transparent one for Signal. The Black for Signal Ground. The Red for +72 and the silver one as -72.
If you want further instructions, send an email to achan@sjc.edu.hk and I will post you the diagram.
The material i use slightly different, i use mundorf silver gold cable on signal, cu plated wire on ground and i add aluminium foil shielding.作者: autumnleaf 時間: 2008-10-15 16:06
I treat cables as equipment because they change the whole system performance in the same degree as replacing equipments. And the market price of branded cable reflects the value how effective the cable being into the formula of sound improvement. Certainly you won't loss your music enjoyment without a decent cable. The market reality is that 10% rise of improvement cost 90% rise of investment.
Some branded cables have too strong their sonic signiture that suit special requirement. Let say if a customer wants more sweet or bass in his system and a particular cable can give him more sweet or bass, then it can charge the customer premium, because this cable inject life into his system or solve his problem. And this is also the reality of pricing theory in the market. Certainly some is affected by "sin 稿".
DIY cable is a good idea if you can source high quality material and have appropriate skill. Just like if you got decent cap, OPT, 300B, it is possible constructing your own amp beating down branded model.
Dear alfcat,
I had tried to "unplug" the battery from my AQ speaker cable. It was really day and night. Without the battery, the sound slow and lack life. With the battery on, the sound became dynamic and had colour on individual instrument. The sound stage was obviously widened.
But the voltage of battery affects the nature of sound. With the 72V upgrade by Radar, the sound becomes too fast in transient that make me nervious. So at last I switch it back to original 24V for right timing.作者: SSWONG 時間: 2008-10-15 16:55
Agree with ALC!
Cable really play important role....a suitable speaker cable & interconnect really can give different life to the system...but comercial good cable too expensive....作者: alfcat 時間: 2008-10-15 23:42
Dear Autumnleafcat,
To tell you a little secret here. I was going to THROW away the Audioquest Diamond back just before I decided to try the battery thing.
As you have said, sound was DULL and quite sound stage is narrow. My colleagues told me about the battery and asked whether I know how it is done. I am not a Physics man so I consulted my Physics colleague. His sharing confirmed my theory and so I go ahead and try it out. The first few hours, no big differences. I left it there for > 15 hours and then come back again. Unbelievable!
I haven't try the 24V, 48V yet. I did make some for my colleagues.
