金前迷思問題.

glitterstc

原本是輕微中毒的我, 是使用環擴的前級推麥記MC240後級, 後來想聽聽金嗓子的系統便購入了金嗓子的合併機E480, 當初是想E480可一機多用, 但原來金記的毒海是不可以回頭的, 一個唔覺唔覺便再買了部A70, 入手A70後又身痕入手了金記C2810 前級.
問題來了, 當我把E480的前級跟C2810推A70來 A-B對比發覺兩機的差距不是想像那般巨大, 想請教高手們如果是換上C2820會否比C2810 更好些.

現在系統是:
前級 C2810
後級 MC 240 和A70
喇叭 B&W 705 s2 signature
解碼 holo audio cyan2

如果480嘅前級同2810, 你都唔覺有乜大差距, 可以唔使換2820了.

其實都想了解C2810和C2820差距, 因為店家可幫忙找C2820 補錢升級, 但換了C2820後就不能又換回C2810.

其實無咩可能, E480係好舊款了. 佢份前級真係麻麻地. 部金前應該係完勝E480.

問題來了. 建議你先找出那個位置令聲音無變化. 例如我既經驗係前去後級的接線, 喇叭線等等.

我試過因為條喇叭線與喇叭不配合, 令我在前端換咩線, 咩機, 都好似無咩分別.

又試過條前去後條IC, 都係同樣問題.

當然大前題係你對喇叭有無能力出到應有的分析力. 又係另一回事.

所以音響就係咁好玩.

你可以分享你依家用緊既線材與喇叭嗎?

現在喇叭是B&W 705 S2 signature 書架，DAC到前級再接後級都是用 AudioQuest Mackenzie xlr cable, 喇叭線是AudioQuest Rocket 44 bi amp cable.

Seems like you are using CAS or streamer as music source, is that correct?

Does your Holo DAC have polarity switch? The Holo DAC XLR should be using US standard, 1-Ground, 2-Hot, 3-Cold,  The Accuphase Preamp using the Japan XLR standard, 1-Ground, 2-Cold, 3-Hot.

You need to switch the Holo DAC to negative polarity/out of phase when connecting it to the Accuphase Preamp using balanced connection, if your DAC does not have polarity switch, you can switch the polarity of your Accupahse preamp. If not do so, you are listening music in out of phase in most of the time, that would degrading the performance........

回foxtan 兄,我是用qobuz 串流,  而E480, c2810和A70是調了美式相位, 而沒有調DAC的相位, 不知這有沒有影響？
