Great product
Although I didn’t use it, it arrived on time. I opened it up and it was sturdier built. I only returned it because I wanted my preamp to match my fosi amp.

Serious power for the size; the sub frequency knob is great
This is a mono (1-channel) audio power amplifier, but provides one full-range speaker 50-watt powered low-level output, and one subwoofer passive (mono RCA) output. I hooked it up in concert (Daisy-chained) with another 2.1 channel amplifier, and it sounds amazing, when I synced the timing.

Excellent amplifier. Meets or exceeds marketing statistics and has cool features!
Electronics engineer’s review will be coming soon ™As a consumer, the A70 just works. It is a great amplifier with some really cool features I never knew I needed.As far as I can tell, it meets or exceeds all its specifications for TDP, power output etc. I will be evaluating this in more detail under different loads at a future date so for now I will cover more of the cool features:1. XLR is a nice to have. I don’t personally have any in my setup but occasionally I have used it for odd or specific setups.2. The +6db is REALLY nice. Some audio sources are really quiet. The worst offender is an LG TV that automatically drops the volume every 30 minutes if you set it above a certain level in the UI. The trouble is, the TV doesn’t actually know how loud the room is so this may be going from a comfortable volume to nearly silent. The +6db allows you to get the full range out if this amp with such sources.3. The built in crossover is cool. Not used as I have a full equalizer for room calibration but I can think of times it would be useful.4. The 12V trigger is awesome! I cannot wait to build a custom controller for this that allows it to be switched on and off with the rest of my setup to allow for energy savings.I really only have two gripes:1. AIYIMA already has a product with the name “A70” which could be confusing. They also advertise this as being used for 7.1 surround setups, but having 8 of this seems like it would require excessive tinkering to get a room to sound good compared to an all-in-one receiver that is programmable.

Powerful clean sound, no pops, versatile amplifier
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

Very low power in subwoofer mode
I was completely puzzled by this (mono/sub) amp as in passive subwoofer mode it barely output even 10w power at max volume and max filter settings. The same RCA input on Fosi Audio TP-02(sun amp) was working perfectly fine and was plenty of lows at just 10 o’clock volume position. I also tried Fosi Audio M03(mono/sub with more power on the paper) and it was not as powerful as TP-02, so volume was at 11 o’clock position to have the same lows output. I was looking for sub amp with trigger to automate on/off, but no luck with this one.

Perfect feature for a mono block amplifier
Perfect feature for a mono block amplifier! Capable of connecting two subwoofers.

Das ist die Zukunft der TPA3255 Amps, diese Endstufen haben keine der Eigenheiten der einfacheren Konstruktionen, sie sind extrem sauber im Klang, arbeiten mit sehr verschiedenen Lautsprechern hervorragend zusammen, und haben wirklich Leistung ohne Ende.Auch die Lautstärke auf beiden Endstufen gleich einzustellen, ohne sie voll aufdrehen zu müssen, erwies sich als viel problemloser als gedacht, erstens sind die Regler gerastert, man kann also mitzählen, zweitens sind die Lautstärkesprünge pro Raster genau so dosiert, das man sie gut hören kann.Sie werden kaum warm, weniger als jeder Transitorverstärker, sind komplett leise, also weder Rauschen noch Knacken beim Einschalten, noch sonst irgendwas.Mitgeliefert werden richtig gute 48V/5A GaN Netzteile, eine neue Technologie, die kosten einzeln schon um die 50 €.Eine gewisse Möglichkeit den Sound zu beeinflussen hat man mit der Wahl der Eingänge, RCA ist dynamisch etwas limitierter, und sanfter, XLR ist wirklich SO sauber, das man denkt die Anlage wäre kaputt wenn eine Pause in der Musik ist, so ruckartig passieren die Klangereignisse, ohne jede Vorwarnung.PS: die ersten paar Stunden klangen sie noch etwas scharf, das war jetzt am 2. Tag weg

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。

Top Gerät für das Geld. Habe zwei davon in Betrieb, ich höre keinen Unterschied zu meinem Marantz Vollverstärker aus den 2000er. Super, was die Chinesen da auf die Beine gestellt haben.

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。
