meine Begeisterung hört nicht auf, absolute Kristallklare Klänge ,gepaart mit viel Leistung auf meinen Standlautsprechern ( Nubert Nu-Vero 14 ),allerdings habe ich mir noch zwei Netzteile mit 10 Ampere besorgt.Leistung satt kann ich nur sagen, wie gesagt ,betreibe ich diese Winzlinge über meine Standboxen.

MONOとFULL Rangeの切り替えは本体裏側のスライドスイッチで行います。サブウーハー用のアンプとして使っているのですが、使い始めの際にこのことに気がませんでした。また入力端子がRCA、XLRが一つですからプリからのMONOへの変換に注意が入ります。3.5㎜のミニプラグからRCAステレオ変換ケーブルを使う際はショートに注意が必要です。音は刺激が少なく、穏やかな良い音です。RCAで有効な+6dBのゲインアップがやくに立ちます。

2.1ch化の為、FX-AUDIO D802++を aiyima A80に置き換えし 暫くD802++をSW用として使用しましたがA80に対し体幹の弱さとサブウーハ用フィルター無しなので中低域の音被りが気になりこの製品を追加購入しました。【購入条件】・TPA3255とPFFB (A70ではAMAZON画面でも明記されてました)・ACアダプタの大きい物 出来れば48V GaN素子 (ユーザーレベルで音の良さ実感できる)・サブウーハ用のフィルター有り出来れば可変可能な物・当然 お手頃価格・出来るだけ低インピーダンス駆動可能な物・なるべく使わない機能が無い物同価格帯のライバルメーカの物もヒットしますがA80の音が気に入っていたのでAIYIMAです【開封、外観】AIYIMA AMPシリーズ共通の緩衝材入り化粧箱でシール有り(AMAZON簡易袋入りでした 最近AMAZON箱少ないですね) 多分、単品の大陸発送では無かった様なので箱の大きな潰れ等無くて良かったです。・MONO AMPですが 大きなVRとトグルSWをシンメトリック配置して見た目も意識されてます・現物触った感じでは質感は値段相応だけどVRを回した時、デテント風のクリック感有りますただ 大昔に購入した東京光音のカチカチとしたあの感じでは無くグリスにどっぷり浸かってる感じです。 (トグルSWの方は取付先がそれなりで本体が軽い為、残念な感触です。)お手頃AMPに質感求めてもお門違いですねすみません 操作上の支障は全く無いので安心です。【産声】現時点でTPA3255+PFFB + 48V 5A (GaN) この価格帯で間違いの無い組み合わせだと思いますサブウーハ用として使用してますが A80(DAYTON PC83-8駆動)をしっかりサポートしてくれてます。メインが10cm以下のサブウーハ用のampとして駆動力ではアナログampもはや必要ない気がします。車だと万年渋滞路を大出力MTの旧車で細心の注意をはらって運転するのとただ踏むだけで軽快に走るコンパクトEVに乗せられている位違う気がします(嗜好品としてどちらが楽しいかは別問題ですが)・中華製 D級ampでもTPA3255の採用はもっとお手頃AMPでも有りますが電源が32V以下だったりハイカットフィルタ機能無かったり、又はトーンコントロール付きだったりするとクオリティが犠牲になってたりしそうなので、自作で何とか出来る方以外はA70 MONOは それなりの音質確保を考えるとお手頃価格の有力候補に出来そうです。・現状でNFJ 10cm SWx2を駆動するには十分です VRとフィルターの効きも調整出来るので曲によって弄ったり メインのユニットを比較試聴する際に大きなツマミが使い勝手良いです。

This amplifier has loads of improvements over other similar amplifiers:- Beautiful Solid case work with sufficient size and spacing between connectors- Very powerful and clean sound with +6dB gain for RCA connection- Active subwoofer output with low pass filter adjustment- Mono full-range amplifier and sub-woofer amp modes- 12v trigger inputs works well with my DACImprovements:- No pop sound on power on/off, every other amp has this issue but not this one- Does not heat up like others, somehow better thermal performance- Good quality speaker connectors, I am using 12 AWG wires without any issuesHIGHLY RECOMMENDED
