- True Tube Amplification: The preamp circuit elevates the voltage to 54V, ensuring the tubes work to their full potential, delivering a warm and rich experience. The unique preamplification technology delivers pure audio signals, faithfully reproducing crisp high tones, full midrange richness, and deep, rhythmic bass. (Important Tips: Remove the copper rings for effortless installation of the tubes on the P3.)
- Bluetooth 5.1: Equipped with the Qualcomm QCC3031 chip, the P3 preamp guarantees impressive wireless sound quality and low latency, with compatibility for aptX HD and aptX LL codecs formats. Furthermore, the inclusion of a manual reset button prevents accidental connections by others, enhancing connection reliability.
- Versatile Connectivities: The P3 provides Bluetooth/RCA inputs and RCA/AUX OUT/3.5mm headphone outputs. It can help create a 2.1-channel audio system by connecting active speakers/an amplifier and a subwoofer. As a headphone amplifier, it supports headphones with impedance ranging from 16Ω to 300Ω.
- Premium Components: It utilizes ELNA audiophile-grade capacitors and taper A pot. The bass and treble controls boast central detents for tone-defeating. With an SNR of up to 103dB and a crosstalk of 95dB, it helps form a HiFi audio system when paired with the V3 amplifier of the same series.

After receiving my P3 Xmas gift on the 9th of Jan 2025 it has taken a while to set it up for use.
Yesterday 12 Feb 2025 was the first time that I could really test and enjoy the unit.
I am amazed at the quality of the sound stage that it creates.
Yes it is made to run with the V3, but I added it in between the ZD3 and ZA3. There I could hear the difference between the XLR and RCA outputs.
I was very impressed with the results and the awesome warm sound.
I will do further tests with my V3 and P3 while using the ZD3 as the DAC.

Amazing product! It really elevates the experience of listening to vinyl!

Thanks to FOSI Audio staff for all your help creating my dream setup. I was advised to add the P3 PreAmp to my second BT30D Pro, which runs my rear speakers and is fed by the pre-out of my first BT30D Pro. The difference is night and day; everything sounds balanced, and the quality is amazing, when we are listening to music it’s like we have a live band playing in our front room. Everything is so crystal clear.
My front speakers as mentioned also powered by a BT30D Pro, with the input coming from my TV’s optical port via a DAC, then through a CYP delay unit to synchronize all the speakers. This setup allows me to run my soundbar, which has two fronts, two rears, and a sub, alongside the two BT30D Pros. Altogether, I have 8 speakers, 4 subs, 2 BT30D Pro Amps, and a P3 PreAmp connected and synced to my TV.
The setup from here involves two passive speakers and a passive sub connected to my first BT30D Pro. The pre-out goes into my P3 PreAmp, then into my second BT30D Pro, which runs two passive speakers and a powered sub in my front room. The passive sub output goes to a sub in the room directly above to block out noises from my noisy neighbours. They have an industrial combined dryer/washer attached to our front room wall. After kindly asking them to move it and being told to go stand in the garden while it's on (tricky when it's on nearly all day until 9 pm), I devised this setup to completely block their noise. Now we can enjoy watching TV again this time with cinema quality sound with absolutely no interruptions and they can do what they like as we wouldn’t hear their noise pollution even if they were having a party, .
The system as a whole exceeds my expectations, and I am thrilled I chose FOSI Audio for my amplification and pre-amplification needs. Having previously DJed with Electro Voice ZLX-15P’s, I can confidently say the FOSI Amps offer far higher quality sound. You can hear every note, and they definitely blow the cobwebs away. If we turn them up, you can feel the wind from the speakers as the FOSI amps are incredibly responsive. The clarity is unparalleled. I am extremely pleased, and I had to write this review to thank the FOSI staff team. You are amazing, and I wish you all a very Happy New Year.
I've also made a short video, which I sent to FOSI Audio, showcasing how my setup turned out. They've told me it will be added to the FOSI Audios shorts section on their YouTube channel, which is an honor. The video is too big to upload here, but I'll share some pictures. Thanks again from a very satisfied customer who will definitely be back.

I am very pleased with the audio output of this unit. I connected the Fossil blue tooth to my cell phone that has 1000+ music files. The output from the Fossi connected directly to my Sansui SD5000 Reel to Reel via the RCA connection. I recorded many of these songs to the Sansui. The tone controlls on the Fossil greatly enhanced the fullness of the music. Many of the songs were from the 50s and 60s and sounded much better after recorded with enhanced tone. I highly recommend this Fossi P3 .
