🎶 Fosi Audio P1 Tube Pre-Amplifier Mini Hi-Fi Stereo Buffer Preamp 6K4 Valve Vacuum Pre-amp with Adjustable Treble and Bass Tone Control for Enhanced Home Theater and HiFi System Experience Review

I installed a sound system in my garden and used a bluetooth receiver connected to a Dayton Audio APA150 to power my outdoor speakers. The sound was ok, but the Bluetooth power wasn't enough to exploit the full potential of the new amp. I added a Fosi P1 tube preamp and what a beautiful difference! I then upgraded the bulbs to a GE JAN 5652W kit and WOW! The sound quality is perfect! It also affected my family. I love that this particular Fosi preamp has treble and bass controls to tweak the…

My "Fosi Stack" with custom RCA cables and twisted pair speaker wiring. Via the USB interface from my laptop to a Fosi DAC. Well, I definitely like the compactness and the surprisingly good, clean, quiet and detailed sound quality for my desktop. It kind of blows my mind. I'm pushing in some old Polk LSi7s and a BIC F12 subwoofer, HOLY SHIT! The 50W x 50W V2 is plenty for this near-field desktop setup, and the P1 tube preamp sounds great and delivers an amazing soundstage. I definitely…

I was about to withdraw my 3 star rating because the preamp was able to add a nice touch to the sound and I kept it. At first it was almost returned because it didn't work. I raised the stars out of a sense of justice. HOWEVER, I WILL NOT USE CAPITAL LETTERS TO MAKE MY POINT. Pipe heat is exactly that. It's not the same as flavoring the highs and lows (which makes this unit excellent for a sub-$50 unit). If tubes are used in the amp, this should smooth out the waveform; This mitigates the cold,

I thought my system was pretty good before I added this little gem. Using a very high quality 60WPC stereo amp on some bookshelf speakers I was happy with my setup, but figured for less than $50 I could try and see if adding "tube sound" to the system could improve the soundstage . I was blown away by how much extra clarity and power this little preamp added. I've done several AB comparisons and there's just no comparison; This Fosi P1 tube buffer definitely improves the sound quality, clarity,

I recently updated my setup and needed something to smooth out the rough edges. After years of legendary rock concerts and raucous live sporting events, my ears aren't what they used to be. was. Mid-bass was absent while the highs were harsh and commanding. After reading positive reviews about Fosi P1, I decided to give it a try. Connected to Marantz CD6006, Audiosource EQ200, Hiby R3 Pro Dap with Fiio Kilaminjaro headphone amplifier. and a Taotronics Bluetooth transmitter, an Emotiva PT-100…

After years of thinking about tube amps, I finally decided to look into them. To be honest I was still skeptical. When I saw an opportunity to buy a tube preamp for less than $50 I thought why not. I've known the quality of Fosi since I bought one of their bluetooth stereo amplifiers during their Black Friday promotion. When it arrived today I put it between my Focusrite Scarlet Solo and Yamaha studio monitors. I turned it on and the sound quality improved immediately. I know it's cliché to say

When thinking about the difference between a tube and a semiconductor, save time by simply choosing SS. The Tube is rather nostalgic and because of that I really wanted to like this preamp. Whilst I really like this preamp and it is such good value for money if you own another current amp like Schiit, Creative, Topping, JDS etc then you really don't get anything more than having this preamp. The equalizer is amazing. It's so good that I ended up buying a JDS Subjective 3 so I can play around…

Probably the cheapest and best upgrade you will ever find! My system is an old Denon 3803, some Infinity R162 bookshelves and an Elac s10eq subwoofer. Stream from Alexa Echo to preamp and then to Denon. I bought two different brands/preamps. both are high quality. I prefer the Fosi for its simplicity and RCA inputs, plus it's a bit cheaper. I've never tried standard tubes but replaced the tubes in the Fosi with vintage 1974 GE NOS tubes, the clarity of the sound was the first thing that struck…

Only 30-40 hours of listening time on the device. Installed GE 5654 lamps at power up. My first reaction was that this device affected the sound quality much more than the buffer it replaced which failed. Eliminated height issues with my analytics system, which tends to be more positive, as well as my room, which exacerbates the issue. I have some #6AK5 RCAs that I can replace later if I find any artifacts I don't need. The unit delivers tighter low-mid/high bass that compliments my speakers…
