- Fosi Audio P3 Tube Preamp Headphone Amplifier Home Audio Preamplifier Mini Vacuum Pre Amp Receiver with Bluetooth aptX LL HD Bass Treble Tone Controls for HiFi Stereo Active Speakers with RCA AUX Jack

For those who aren't aware of what a tube amp is..it's quite simple. It makes your audio feel warm and fuzzy, it loses its sharp edges, the treble, mids and bass all soften and are more pleasing to the ear. The Fosi Audio P3 does well for its price segment and has a great quality output connected to my Fosi Zk-1002D budget amp. This preamp is a no nonsense device which provides normal treble levels and deep soft bass output. To be honest, I found the sound off initially since I was so used to the edgier sound of a direct amp, but trust me it grows on you quick.

Lovely little piece. Was messing with my beolab 4000s and decided to buy this on a whim. Its tamed my speakers, made it more mellow and warm. Love the sound. Needs to be cranked up a bit to drive them though

I have been following fosi products. There are mixed reviews on Reddit and youtube some just branding it as cheap chifi setups. I wanted a Bluetooth transmitter and I was eyeing on fiio but that was costly so this was another option. I didn’t need an amplifier though. So this preamp was a good option. I personally like old vintage songs and warmth. So tube amps were a good option for me. The only question was whehter the build quality and sound quality would be good? Once I received, I connected it to my studio monitors and I could understand the warmth from the tubes. Then I listened to it by connecting on my IEMs, warmth is noticeable. The music becomes more enjoyable to hear. Soundstage is not that wide. But the bass and treble controls are really nice. Bass noticeably gets boosted at 12 o clock position. The volume button increases non linearly. It has enough amplification for IEM that I never get past the 12 o clock position, so I guess it would be able to drive full sized headphones also. One con would be when there is no electricity and when I play it on the inverter there is a hissing sound (some kind of weird earthing issues Iguess, because same thing happens for my studio monitors also) Conclusion - it has impressed me with the sound quality and build quality. Maybe better tube amps will be out there but this one is a good starting point.

Superb quality of audio

Super item

Will come with Chinese 6J1 tubes . Not 5654W tubes as told in description . At least in India

Small, built well and a no nonsense preamp with bluetooth. Treble bass controls could have been bigger with better feedback. And the off function should be in the middle that way I can turn on off it without going through multiple clicks. It matches well with my A07 max and A5 pro

Excellent Product! I have connected it to my Fosi Audio HT4S Amp and believe me, it made the sound quality SO REACH, beyond expectations!! The depth what you can achieve is mind blowing. Thanks Fosi Audio team who helped me in some basic queries and it’s one of the best purchase I experienced. Thank you

Prodotto di altissima qualità, perfetto per ascolto di musica ad alta definizione. Lo ho abbinato ad un amplificatore Yamaha S-A201 e suona perfettamente, riesce ad aggiungere quella nota di calore che manca all’amplificatore.

Uzun zamandır fosi audio ürünlerini satın alıyorum. Zamanından önce teslim ettiği için Amazon'a ve de kaliteli ürünleri uygun fiyatlarla sattığı için fosi audio ' ya teşekkürler. Bu cihazı; Fosi' nin BT20A pro amfimin çokta parlak olmayan sesine katkı sağlar ümidiyle aldım. Genelde yorumlarda V3 ile eşleştirenlerin yorumlarıni görünce satın alırken biraz tereddüt ettim. Çünkü bu amfilerin zaten bir preamfi özellikleri vardı. İkinci bir ön amfi ile nasıl eşleşir endişesi taşıdım. Ama sorun olmadı. Bağlantılarını yaptım ve çalışmasında herhangi bir sorunla karşılaşmadım. Bu cihaz, BT20A pronun sesini daha açık hâle getirdiği gibi bas ve tizlerde de belirgin bir iyileşme sağladı. Bazı yorumların aksine tüpleri yuvalarına yerleştirmek iki dakikami aldı ve takarken hiç zorlanmadım. Bu arada bir tespitte bulunmakta yarar görüyorum. Bu cihazlar küçük ve her bağlantıyı bu kutucuğa yerleştirmek zor olabilir. Ancak yine de preamfi katıni daha kaliteli yaparak ve fiyatını o oranda yüksek tutarak insanların sürekli başka cihazları satın almak zorunda bırakılmaması yararlı olur diye düşünüyorum. Ancak bu tespit ve öneri; Fosi' nin işine gelmeyebilir. İlave özellikleri olan cihazları üretmek ve çeşitlendirmek günümüzün bir satış politikası olabilir. Ama yine de fiyatı biraz yüksek tutarak daha entegre edilmiş ve ses kalitesi artırılmış cihazlar üretmekte iyi bir pazar yaratabilir.

この商品は、インテリアとても良いと思います。 まず真空管部分ですが、通常はオレンジ色の電球色のみですが、青混じりで光ます。 音に関しても充分な出力があり絞って使用しています。 間に改造修理したイコライザーをかませていますが相性バッチリでした。 DACからイコライザーに繋ぎイコライザーから二つのアンプに分岐して電源Switch切り替えでヘッドホンとスピーカーの切り替えをしています。スピーカーの音とヘッドホンの音が近い音質で聞こえるので違和感なくかなり良いです！！ pcの純正ジャックに繋ぐと同じイコライザー繋いでいない為音が違うのは当たり前ですが、やっぱり耳に突き刺さりました。 それぞれ個人独特の環境作るのに役立つと思います。

My old and very cherished 1980’s music centre recently bit the dust, so I was looking to replace it in a cost effective way, but could not justify spending a fortune on an expensive amplifier which would only see occasional use, so after reading a few favourable reviews , I bought a Fozi V3 amplifier . I was a bit disappointed when I hooked it up to my Vintage Celestion speakers and connected my iphone to it to find that the sound was very underwhelming with a thin reedy sound so I put the V3 back in its box and forgot about it for a few months. One day , after a bit of googling I realised that I needed a pre-amp to boost the signal from the Iphone so I bought this Fozi P3 pre- amp for not a lot of money , connected it up to the Iphone / V3 amp /Celestion speakers and Wow ! , what a transformation. It sounded great . Inspired , I collected up all my old audio stuff, like a JBL 300 watt sub woofer I used in the car years ago, and I now have the best sounding sound system I have ever put together. With plenty of top end from the tweeters , I can really hear the high hats coming through , combined with earth shattering bass from the 300watt powered sub it sounds great . For the money, I think that this Fozi audio equipment is absolutely superb and fantastic value. This is an honest review, I bought the Fozi V3 and P3 with my own hard earned cash . I am really enjoying listening to music again !

Fosi P3 Calidez analógica. El último lanzamiento de Fosi Audio se trata de un previo a válvulas que añade una calidez que parecía perdida en el actual mundo digital ¿Qué nos ofrece el P3? Se trata de un previo analógico que permite la conexión de un dispositivo con señal de línea RCA y un dispositivo bluetooth, el P3 incorpora versión 5.1 Estéticamente se trata de un conjunto bien conseguido, donde las válvulas de vacío destacan en la oscuridad gracias una discreta iluminación de tono azul. En el frontal dispone de un selector de palanca que nos permite la desconexión del dispositivo y la selección de fuente, un guiño a los selectores de hace unas décadas. Además, dispone de un control de graves y agudos que permite ajustar el tono de la señal, una muestra de su calidad es que tanto en su posición mínima o máxima la señal no es distorsionada, recordando la ecualización de las mesas analógicas de alto nivel. En cuanto a salidas dispone de salida de auriculares en formato 3,5 mm. salida rca procesada por las válvulas y una salida aux. en formato 3,5 mm. para alimentar un sistema aux o subwoofer. Los datos de la salida para los auriculares son los siguientes RMS Power: 250mw @16Ω；150mw @32Ω；32mw @250Ω；20mW @300Ω Headphone Impedance: 16-300Ω Para las pruebas de auriculares he utilizado los Sennheiser HD25 y los Fidelio X2HR, consiguiendo un alto nivel de salida sin distorsión. Un detalle a tener en cuenta es que al activar la salida de auriculares desactiva la salida de línea del P3. La señal de línea del P3 puede alimentar tanto altavoces activos como conjuntos amplificador/altavoz pasivo en ambos casos aporta calidez a la señal. El tamaño del P3 es idéntico al amplificador V3 de la misma marca, permitiendo una instalación en conjunto y dotando al V3 de controles de tono y fuente. El tamaño permite tanto una instalación permanente, como una agradecida portabilidad que permite ubicarlo en diferentes áreas. ¿Para quién está indicado? Apasionados del sonido en general y uso de auriculares. Es una pareja perfecta para combinar con DAC`s sin salida de auriculares, mejorar la calidez de conjuntos con un sonido seco y amantes de la personalización del sonido ya que permite el empleo de una amplia gama de válvulas de vacío de 7 pines. La relación calidad/precio inmejorable como eslabón de la cadena de audio y unas muy buenas características técnicas.
