上一篇提到8010a+7040a感想
這次補上目前訊源系統(D90MQA + Pre90)的感想,跟抉擇時的心路歷程
這邊引用上篇AerobladeIII兄的推文心得做參考
推 AerobladeIII: 8020D+7040A路過,真的舒服。這顆重低音收放自如, 08/05 16:43
→ AerobladeIII: 該炸的時候炸,平時聽音樂幾乎沒存在感但會覺得中 08/05 16:43
→ AerobladeIII: 低頻比單兩件飽和。娛樂性非常高 08/05 16:43
推 AerobladeIII: 想問一下你前級用什麼?我原本用DX7PRO後來升級ADI 08/05 16:52
→ AerobladeIII: -2,分離度好一些,升級感有但不明顯,唯一差比較 08/05 16:52
→ AerobladeIII: 多的是重低音變太強XD 08/05 16:52
現在的話是D90(MQA版)配Pre90
其實A大的ADI-2當初也有考慮過
但當初因為預算只先入手二手D90(MQA版)
用XLR輸出,音量調整用D90的數位前級
感想是中性三頻均衡的聲音很適合讓GENELEC發揮
而且解析層次真的強
不過如果跟其他DAC比的話,的確有點各別樂器結像略模糊
(自己覺得模糊程度比較像口味偏好差異的等級,跟DACmini CX比)
經過一陣聆聽,發現純靠D90的數位前級調音量
有大聲才能聽清楚細節但無法承受音量,小聲又覺得整體聲音很縮的問題
且無法靠 dip switch調整 & 擺位修正
在板上找到關於前級(pre amp)的討論
https://www.ptt.cc/bbs/Audiophile/M.1590475168.A.074.html
以及ASR論壇的討論
https://www.audiosciencereview.com/forum/index.php?threads/
is-a-preamp-needed.10154/#post-276996
歸納問題應該是D90(MQA版)的XLR輸出Vrams不夠(只有4Vrams)
需要前級(pre amp)再放大
這下有點崩潰,因為D90MQA + Pre90價格其實快可以買ADI-2
一陣思考,覺得Pre90在ASR數據不錯 (近乎無音染極低雜訊)
如果真覺得D90不行,Pre90還能沿用
購入Pre90之後,完全解決整體音量問題
也同時被前級(pre amp)的存在震撼到
的確是整體性的提升
現在的話會寧可先買好前級,再慢慢看訊源
沒用前級,有點像喇叭不是用最佳狀態發聲
就算DAC直出聲音聽起來比同等級綜擴強
上了前級後,才會發現之前的聲音不是最佳狀態
像是終於讓喇叭用最佳功率做事情
Pre90本體額外使用心得:
遙控器跟旋鈕都有
而且有記憶音量 & 安全音量真的很方便
雖然是普通的將DAC輸出功率放大
但聲音出來之後覺得前級真的是默默付出的那位
沒了他才會知道他的好QQ
