Review: I'm currently using two of the Aiyima A70 mono amps that work great when paired with Dynasty ProAduio PX2 pre-amp. I wasn't able to run amps at full bore due to sound was too loud. No joke. Previously, I was using a Douk tube preamp which until it went out within 3 weeks of use. I thought sounded good until I decided to paired with the PX2 preamp, and they work really together. The Aiyima is clear and articulate as any full size amp I've had used before. I'm talking about NAD, Adcom, Hafler or Yamaha.And I had them cranked to just over 1/2 where the sound was too loud with no distortion or breakup. No Bluetooth with this amp. I was surprised at the headroom given, and the attack time was spot on. I'm not joking. But how long with these last, no idea. I got these new on sale, one for $118 and the other was $85. I highly recommend, will fill a room 18'x15' with no issues and volume to spare. So far a strong 4.5 amp!

L社の125w/chの4チャンネルデジタルアンプ(定価25万)を本機4台に置換し、マルチアンプで以下のアルテックシステムを駆動した ホーン:803B/1.5インチドライバ ウーファ:402A/オンケン箱 ツイーター:コーラル プリアンプ:Xone92 チャンネルデバイダー:Ashly X-1001 一聴してA70monoの圧勝:音の立ち上がりが峻烈かつ抜けが良くなった。前後の空間表現についてはまだ望む所があるが、この価格、この大きさでこれだけ鳴れば充分合格だ。 これまでのアンプではこの大型ホーンを鳴らせなかったのが明らかとなった。48V/5AのGaNスイッチング電源、PFFB確実に中華デジアンは進化している。 これに、特注のアモルファス、コンデンサアレイをかますと空間表現が増し一気にワンランク上の音になる マルチアンプの場合1chずつ出音を確認出来るのはメンテの場合圧倒的に有利だ。また、各ユニットに付随する音量のバラ付きを考えると各チャンネル毎に音量を調節出来るメリットは大きい A70monoは買いだ。 ホーン:Altec 805B/1inch ドライバ、 ウーファー:Altec 416-8B , エンクロージャー:自作バスレフ箱(120L) プリアンプ:Xone 92 Aiyima 07Max2台から本機に変更した。 XLR/RCAを直に挿せるのは使用上メリットが大きい。また、ON/OFFスイッチが有るのも、アンプパワー設定を保存出来るので便利だ。 07Maxでも”スピーカーが変わった”かの様な出音の改善に驚いたが、本機では更に迫力が加わった感じ(但し電源の工夫が必須だか)。どうも価格22万円の500W/4chのDアンプよりトルクがあり、締引き締った低音が出る印象だ。 結論として4万以下で大型スピーカーを駆動するアンプならこの一択だ。 今のマルチアンプシステムへの変更導入も充実アリだ。
