當然有阿，看了要買喔 :laugh:

:shock: :shock: :shock:

偶就知道會拿這個來 :unbelief: :laugh:





iFi Micro iUSB Power Supply + ifi Gemini

以前其實想買這兩個
可是看到線跟機器一樣價錢我就嚇到了 :jolin:

USB最後一哩，遲早要上的何不現在就上 :laugh:

我比較想知道聽感~有沒有提升@@

個人認為, 買了不要自己換, 要請別人幫你換, 自己閉著眼睛(帶著眼罩)聽, 超過80%辨識率才叫有效.

下面都是Samplng rate
CD 採樣 75Hz-->PC-->非同步XMOS(接收+重新產生clock) MHz-->AK4399 MHz
上述都是數位傳輸, 出錯就是破音或暴音, 太無聊的話可以試著將wav的0,1改看看.
人耳 間隔察覺約~ms=1KHz

5V電壓只要波動0.1V, 就是2%影響.
2. Voltage Reference
The differential voltage between VREFHL/R and VREFLL/R sets the analog output range. The VREFHL/R pin is
normally connected to AVDD, and the VREFLL/R pin is normally connected to VSS1/2/3. VREFHL/R and VREFLL/R
should be connected with a 0.1μF ceramic capacitor as near as possible to the pin to eliminate the effects of high frequency
noise. No load current may be drawn from VCML/R pin. All signals, especially clocks, should be kept away from the
VREFHL/R and VREFLL/R pins in order to avoid unwanted noise coupling into the AK4399.

CD播放機每秒讀取75個扇區
XMOS
AK4399

大大不知道能不能教一下怎麼聽才能聽出這種差異
小弟十分佩服 :shy:

In short, I would have absolutely no hesitation in recommending the iFi iPurifier2 to anybody using a USB DAC or converter to supply the music signal to their hi-fi system.

回台灣記得買阿 :laugh:
