【新品同様】AudioQuest JitterBug FMJ

USBポートに接続することでデジタルノイズを低減し、ジッターやパケットエラーを抑制してオーディオ信号の品質を向上させるUSB ノイズフィルターです。
※使用期間短く、未使用に近い商品
 です。本箱も付属しております。
- メーカー: AudioQuest
- モデル名: JitterBug FMJ
- 筐体素材: フルメタルジャケット (FMJ)
-購入価格:ヨドバシカメラにて、
      定価¥8360で購入
-特長
・内部発生する高周波ノイズを低減し、ストリーミングオーディオのパフォーマンスを向上させる「デュアル ディスクリートノイズディシぺーション回路」を搭載
・ジッターやパケットエラーを低減
・FMJ(Full-Metal Jacket)を挿入することで外部ノイズを防止
・高周波数帯の混入防止USB出力プラグを通してさらにノイズを低減
・USB2.0のすべての仕様に準拠

金属ケースを採用
新しい金属製のケースは前モデルからは最も明白な変化ですが、JitterBugの出力を覆う一見ただの蝶番状の「ゴム」の部分でさえ、JitterBugの改善されたパフォーマンスにとって重要です。
この小さな黒い「ドア」は、実質的に高周波を吸収するカーボンを素材としているため、高周波混入防止となっています。

音質向上
コンピュータ、スマートフォン、NAS、ストリーマー、カーオーディオシステムとUSB入力の間に、1台のJitterBugを直列に接続してください。
さらに音質を向上させるためには、JitterBug FMJのゴムふたを閉じた状態で、2台目のJitterBugを別の空いているUSBポートに並列接続してください。

パフォーマンスの改善
JitterBugをDragonFly BlackまたはRedと直列に接続すると、音楽のステージがより広がり、見晴らしが良くなります。
しかし、DragonFly Cobaltは、JitterBugのフィルターを一部採用しているため、2つのフィルターを直列に接続すると、特定の機器や状況に応じてパフォーマンスが改善されますが、変化に乏しい場合は並列使用することでノイズドレインの役目をします。
