Review on 🎶 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 by Stacy Brooks

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 preamp, a Fosi P1 and an Emotiva Basx-A300 amp. P1 connected between my preamp and amp to work with all my sources (cd player and dap). All output on my favorite 34 year old Polk monitor. 10B floorstanding speakers, Polk PSW505 subwoofer and Klipsch R-10SWI subwoofer for added impact! Set the volume to P1 for about 2 hours, bass for 1 hour and treble for 7 hours and midbass and live and dare! Tight and punchy, just the way I like it, and the highs were soft and smooth with no ear fatigue, even after hours of listening! By the way, I ordered a set with GE5654 tubes and can recommend it to everyone, because they really sound better than stock tubes. Overall I am very happy with this product and amazed that a $60 product can make such a difference in my setup. Highly recommended!
