概要・総評
最大1,400mWの4.4mmバランス高出力、Cirrus Logic社製フラッグシップCS43198 DAC、カスタムVA液晶画面、PS5・Switch向けUAC 1.0モードを搭載した1万円台の据え置き型DACアンプ決定版。ゼンハイザーHD600等の高インピーダンス駆動検証レポート。
メリット (Pros)
- +同クラス圧倒の最大1,400mW+1,400mW（4.4mmバランス）出力でゼンハイザーHD600等の300Ω高インピーダンス機も余裕でドライブ
- +Cirrus Logic社製フラッグシップCS43198 DAC搭載により123dBの高S/N比と高感度IEMでも無音の極低ノイズフロアを実現
- +ハードウェアUAC 1.0切替対応でPS5やSwitchなどのゲーム機でもドライバー不要のハイレゾロスレス接続が可能
デメリット (Cons)
- -Bluetoothワイヤレス受信機能は非搭載で、有線USB、光デジタル、同軸デジタルの高音質接続に特化した設計
- -600Ωなどの超高インピーダンス機をハイゲインで長時間大音量駆動した際、筐体表面がやや温かくなる発熱あり（アルミ放熱設計）
