如題原文
The ALO iMod Portable Vcap Dock, ALO - "Modding the Mod" with the ALO P-Vcap Dock

The ALO P-Vcap docking system uses the highest quality capacitors in the audio market today. VH-audio's Oil Impregnated Metallized Polypropylene capacitors.

http://v-cap.com/oilcapacitors.html

The audio signal is sent via a ALO line out dock cable (sold separately) to the P-Vcap docks mini input. The audio out is via a RCA or mini to be sent to your home amp or portable head amp. These P-Vcap docks are going to deliver the fullest most resolved sound you can obtain from your iMod.

All of these P-Vcap docks are hand built here at ALO and assembled with care fit and finished to give you a sound that will rival expensive CD sources that will cost 2 to 3 times this cost. These feature high quality connectors, point to point wiring with heavy gauge solid silver in cotton wiring. Items included in this package are 1 P-Vcap Dock only, cables must be purchase separately. The P-Vcap Docks I am making today have all the inputs and outputs on the front plate.

IMPORTANT - You can not use a "iMod" cable with the P-Vcap dock because a ALO "iMod" line out dock cable already has caps located in the cable. Therefor you have to use a normal ipod cable with the Vcap dock. We have many to choose from see "ipod line out dock cables" located in the products section. Please email me if you have any questions
imod, amp and all cables not included

這是電容

coupling capacitor, block the DC and pass the AC.
用在op-amp的輸入端,所以這個只能用在IMOD的IPOD上,因為IMOD是直接拉線路出來,沒有將訊號經過IPOD內部的劣質電容.

一般IPOD Line out
訊號-->內部耦合電容-->IPOD Line out傳輸線(一般用的傳輸線,不是IMOD專用的傳輸線,差異在於,IMOD專用的Line out線內部有內建一顆耦合電容)-->耳擴

IMOD Line out
訊號-->IPOD Line out傳輸線(一般的)-->VCAP(耦合電容)-->傳輸線-->耳擴
應該是這樣吧,有錯還請各位大大糾正
