SA300 High Power 2.1 Bluetooth 5.0 Remote Control HiFi Audiophile Stereo Digital Amplifier,Infineon's MA12070 Chip 80W x 2 Class D Power Amplifier,APTX Input,Multiple Equalizer Modes (Black)

These little guys are powerhouses. I use them out on my dock as they are sealed and also to power my indoor speakers, and the subwoofer works well. If you want enough power to fill an area well and aren't trying to blast for a concert, these work very well.

Good sound quality small size but didn't like that the instructions are only in Chinese. Great for desktop stereo system. I paired mine with Echo dot and 4" Dayton speakers .Great mini system.

I usually don't leave a review on the first day I use a new item, but the exception is justified in this case. I bought this integrated class D amplifier to replace a defective Topping MX3. I liked the Topping. It was a revelation when I upgraded from cheap computer speakers to Scandyna MCP speakers, an Argon Bass 8 sub-bass, and the MX3 on a Mac Mini a few years ago. However, the experience when I plugged in the SMSL SA300 this morning (USB on my Mac Mini, BT on my iPhone) was at least as great - jaw-dropping! I never thought my speakers and sub-bass could deliver such crisp, uncompromising brilliance and volume. They certainly never have before. It's like having a new music collection. The tech specs and functions are well documented; there is no need to recapitulate here (remember: no headphones connector). The amp is solid, well-made, and sits on good anti-slip rubber feet. I like the unusual form factor. It takes less space than I expected on my desk. The volume control (the crux of my old MX3) and buttons feel sturdy and high-quality, as does the responsive remote. The only somewhat odd and uncommon thing is the Micro USB connector (a cheap but working cable is included). The manual comes in Chinese and English only. If you are looking for a reasonably powered class D integrated amp with BT 5.0 and a dedicated sub-bass connector, there is probably nothing better to buy, at least not in this price range.

PC→DAC→プリメインアプ(Marantz PM6001)→スピーカー(B.I.C America DV62si) で利用していたのですが、プリメインアプがお亡くなりになったため当機を購入 PC→SA300→スピーカー となりました。 アナログ入力もあるので、CD/MDプレイヤーも接続しています。 音楽はもちろん、ゲームの音声も良い音で聴けており満足です。 なにより大きなアンプがなくなってデスク回りがすっきりしました。 一応サブウーファーが接続できる機種を選んでいますが現在は未接続です。 たまーーに、USB接続の問題なのか音声が変なことになりますが、 ケーブル抜いてつなぎなおすと復活します。

Vraiment bon marché. A ne pas acheter.

よくあるレビューのような万能アンプではない。 基本的に歪がなく耳あたりの良い音だが、線が細く弱い印象。 低能率や大型のスピーカーだとネガな部分が大きくなる。 能率の良い中型くらいのスピーカーがおそらく一番使いやすい。 自分の手持ちだとPioneer/S-55twinとの相性がいい。 Wafedale/10.1, DIATONE/DS-77HRだと難しい。 Celestion/Ditton 66はそこそこ鳴る。 機能的にはてんこ盛りの印象だが実はSPDIFの入力が無い。デジタル入力はUSBかBluetoothのみ。

発熱が嫌なのでちっこいデジタルアンプが欲しくて購入。 ハーフサイズのアナログアンプ使ってたのが馬鹿らしい程十分。
