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

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.

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

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

Performance: I am really happy about buying this product. The Pioneer HTP072 receiver VSX 324 which i own is a bit quiet on the highs and mids.... combining with this pre amp... the music quality is now appealing.... go for it..well built body too. take your time in installing the valves.. slight adjustments might be needed for it's terminal legs to fit into the socket...tweezers or needle nose pliers recommended..

Best substitute for Bluetooth receiver with extra boost

good product,clear voice ,treble and bass super

Just mind blowing change in sound quality .. previously I was using cheap bluetooth dongal with my sony amp.. but after installing this the sound quality change like day and night.. tone control is also decent ..also little bit expensive , Note: I am using sony hi-res amp and bluetooth connected with apx-hd .. make sure u have have good equipment to get good result .. !!

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.
