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

This is tiny but great product. It gives amazing sound output. It had changed my dull speakers to live ones. I had to get a replacement for first arrival. The package was tampered and the item did not work. The replacement is good. It is working as a charm. I'm highly satisfied with the sound output. My dear woofer has started working and sound is pleasant and sweet.

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.

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

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.

j'écoute la musique sur Deezer et mon PC + Dac Q6 fosi + Préamplificateur P3 fosi + Casque AKG K240 studio.... Que dire... Du bonheur. Qualité/prix fosi imbattable. Ah, j'oubliais,... enceintes actives Argon audio Forte MKII + 2 caissons de grave... Tout ça pour écouter sans casque évidemment... Encore que du bonheur... Voilà, voilà,... Que la musique est bonne.

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 5.1Estéticamente 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 siguientesRMS Power: 250mw @16Ω；150mw @32Ω；32mw @250Ω；20mW @300ΩHeadphone Impedance: 16-300ΩPara 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.

Fick min Fosi P3 idag. Oerhört kompakt format, väldigt bra finish på produkten. Skruva av kopparringarna innan du kopplar i rören. Det underlättar betydligt. Bra och och välfungerande bas-diskantkontroller. Bra känsla i reglagen. Den ser riktigt tuff ut med de glödande rören och ett blått "bakgrundsljus" i röruttagen. Även jacket till hörlurarna är upplyst med blått ljus. RCA ingång med RCA och AUX utgångar. Jag använder den i samband med konvertering av vinyl till digitalt format. Skivspelaren är kopplad till en Behringer 204. Mycket nöjd med den med. Alltsomallt, mycket nöjd med köpet - båda tummarna upp.

good bluetooth connectivity and mediocre sound processing ... I use mine in line with the X2 preamp for my turntable. Well built
