paine 寫:因為有耳擴,
所以我在家用X5L一向用LO(line out)輸出到耳擴,
剛剛去逛逛head-fi和iAudiophile.net論壇,
卻發現原來X5的line out一直都有低頻衰減問題,
馬上測試,把X5所有EQ、音效處理都關掉,
(其實我一直都沒開那些),再把音量調到最大40,
接上耳擴,HP(head phone)和LO比較,
原來我這幾個月都在聽沒低頻的音樂
不過,我本來就對低頻需求就不大,
加上之前用ER4S,低頻聽起來就偏瘦,
一直沒發現這問題
好在X5的HP輸出作的還不錯,幾乎沒底噪,
現在都用最大音量用HP接耳擴聽。
paine 寫:你是金耳,
我是木耳,
OK?
常理說,HP應該是經過數位放大,
而LO則是沒處理過,較乾淨,
之前,我只是認為HP因為有處理,
所以低頻量較多,沒想太多,
自然接LO到耳擴聽,
今天說出來,
只是提醒同是X5用戶的網友們,
不要重複我木耳的錯誤,
卻被你酸???
而且,我自己有親口說很好聽嗎?
妳憑什麼預設我的立場,
大家想換器材,就是為了聽到自己想聽的音樂,
今天提出了,那麼有些人可能就不用為了低頻,
去換線材等等,只要換個HP輸出就好。
koffman 寫:奇怪我聽起來怎麼覺得Line out好很多,聲音乾淨很多,低頻也很好。
Line out一定要接耳擴,直接聽聲音一定不好,功率不夠,只是聲音大聲罷了。
koffman 寫:老實說我覺得X5L聲音不怎麼樣,方便而已。
用不同的線Outline接出來確實差很多,
但是LineOut欠缺低頻我是沒有聽出來。
人云亦云的人很多,上面哪些連結也不
怎樣,不過是用英文寫罷了。
Zephyron 寫:Its true that lower impedance will cause a rolloff on the X5's lineout, and high impedance solves the problem, but folks tend to use them with earphones or headphones in portable situations that in general, have a not so high impedance (e.g IEMs, the highest of which is the Shure e5c so far, with 110 Ohms). Even through the line in of an amp (maybe say a 92 Ohm impedance adapter mini-to-mini cable), the bass rolloff is audible.
The X5's lineout is flawed anyway, so its best to just use the headphone out to do the amping.
How much load does one need when one's on the go anyway?
benA11 寫:32歐姆的阻抗對lineout來說太低了,他無法提供大量的電流做為低頻的長時間輸出(半週期長)是很正常的。
且原po也寫道:Zephyron 寫:Its true that lower impedance will cause a rolloff on the X5's lineout, and high impedance solves the problem, but folks tend to use them with earphones or headphones in portable situations that in general, have a not so high impedance (e.g IEMs, the highest of which is the Shure e5c so far, with 110 Ohms).

建議樓主還是自己測試一下會比較好。
另外,我是新手,剛到貴寶地請大家多多指教,如果有錯也請多包含。
