不過我發現你買的Cipher cable是V1的耶,iSine10/20目前出貨是附V2的Cipher cable了 V2跟V1的差別如官方公告所說: What’s new in V2? 1) It is almost 50% lighter and about 20% smaller than the previous version, making it more comfortable. This change was made based on user feedback from the Head-fi community. 2) Fully balanced headphone amplifier! - The new Cipher V2 has been designed to operate in fully balanced mode. This means that the cipher V2 delivers double the voltage swing for greater output levels. 3) Improved DAC and DSP sections - Improves on the already good Amp and DAC for a more transparent sound and adds an even more powerful DSP. Sample rate and bit rate support remains the same. 4) New Apple LAM2 chip platform - It also uses the new Apple LAM2 platform for better efficiency and lower power consumption. 5) Dual microphones -- It has two input microphones for clearer voice calls. And the iSINEs were already recognized has having the best call quality of ANY made-for-Apple headset. 6) Four buttons - A fourth button allows you to mute/un-mute the microphone during conference calls. This is also programmable for additional functions in the future. 7) A new App to go with it - A new app called “Audeze HQ” accompanies the new Cipher cable and can be downloaded from the App Store.
