請問，睇一個headphone AMP 的spec時，如何分辨佢夠唔夠力推一些所謂難推的headphone？ ...

留意綠色部份.

HD650 好靈敏, 應該好易推..

Volt or power 都可用黎計 amp 輸出, 如何果係 volt 咪 w = v2/R,  = power 咯~ R= loading 既阻抗..
所以理論上 loading 越低輸出 power = 越大.
不過 phone amp 一早已經係用高阻抗輸出計算.. 自己就番條數計咯..
仲有最緊要係耳筒在同等輸入電壓時的輸出音量分貝 (dB), 呢個數值就係佢既靈敏度.  越大越高, 相差 10dB = 10倍, 20dB = 100 倍....etc..

帶個HD600比我試的"好同事"，佢叫我平平地去淘個1:1老翻LehmannAudio。原裝正貨一千美金，山寨一千人仔唔洗 ...

翻得好.... 講真呢 d 線路大圍野又簡單, 都唔明鬼佬野可以賣咁死貴..
淨 headphone amp 計, 淘寶價我都覺得 $500 左右就合理.

D個掂唔掂呀，900人仔唔洗....

呢個都唔錯, 之前我都有睇過資料, 不過就冇聽過.
呃晒你都係幾百蚊, 又可以加錢揀聲...

正話認真少少駁左個淘寶人仔 420 蚊既解碼耳擴駁 CD 聽下(經跟機同軸數碼線) , line out 輸出弱左少少, 但耳筒 out 就唔錯, 明顯好過部 CD 機既耳筒 output.  咁既價錢都算超晒值啦!

我推薦既係大眾價錢平野... 如果你要求太高就唔岩你... 買下面呢 d amp 加對 Stax 靜電 headphone 一定唔會點錯......

note只合適32-60歐耳機，HD600唔合適直接note聽音樂。
