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

For me the valves/tubes were very easy to fit, didn't need to remove the copper ring. Fosi must've listened to feedback and improved their processes. Build quality is very good. Case Is nicely anodised and smooth rounded corners. Looks the part. The sound Makes digital music sound more analogue. It doesn't smother the sound, but makes it that bit sweeter when required. It isn't like dumping 1Kg (2 pounds!) of sugar on your strawberries, for me it's a tiny dusting with a little cream just to dress it up. If that's your thing then go for it. If you don't think you don't want the sharp edges smoothed off a little it's still worth trying. You might like it. The switching and de-thump is very well managed, no pops and nasty clicks, helps protect your tweeters if you use it to drive a power amp like I do. Things that can be improved An extra input, say 3.5mm would be very welcome for another source. And a low pass (sub) output for those with a subwoofer. Perhaps that can be a new product for Fosi?

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 !

As others have said, the valves are a nightmare to fit. TOP TIP:- I used a nub of blutack to take an impression of the valve holder and then a small socket set socket to get the valve pins set to the right diameter to match the holes in the blutack impression. Without doing this the valves were never going in. I have played with, and modified, valve amps for 40+ years and never had such an extreme problem. The amp has very little gain, there was certainly no chance of pushing the power amp, not that you want to break the signal up, but the gain was almost no different to the line signal. The resulting sound is fine. Nothing unpleasant. It doesn't make you go "Wow!" either in a bad way or in good way really. It seems reasonably articulate, with no real vices, but it would be nice if it had a bit more "Wow!" I have seen reviews that suggest the headphone socket is a waste of time because of the lack of available gain. I haven't used it. I also haven't used the Bluetooth either so can't comment on any latency or quality in that respect. It is nice and compact and does the job I bought it for ... and it costs less than £100. Am I happy? Yeh, I guess, it's just not the sort of thing you say to people "Come and listen to this. It's awesome." It's fine.

Great build quality, excellent Matt finish. Very nice ice blue led for the valves. Clean sound and great Bluetooth performance. A bit of tube/valve rolling is worth it if you want different sound signatures. The P3 will feed any power amp with a nice clean signal. I will be trying it out with a few different power amps soon like the Tibo PA150, Aiyima D325X etc. Very handy little pre amp and worth having in your sonic arsenal.

Sounds very nice. Very easy to set up and my phone found the connections straight away. I now have a few Fosi amps and preamps and they are very high quality for the money.

One of the best budget amp crystal clear sound amazing

What it does, it does very well. Basic RCA input or Bluetooth and RCA and 3.5mm headphone output. Audio quality very good. Easy to connect iPhone. Would have been useful if it had a toslink optical input.

Further to my last review, Fosi Audio has kindly sent me out a replacement unit. This one works fine and is a big step up from the one I was using. At the moment I am using it with a cheap class D amplifier, maybe I will upgrade it to a Fosi Audio V3 with 48v power supply when I can afford it. Great customer service. Thankyou Fosi Audio.

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 5.1 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.

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
