Review on 🎧 Fosi Audio P2: Vacuum Tube Headphone Amplifier for Unmatched Hi-Fi Stereo Audio Quality with Low Ground Noise and Output Protection by Derrick Bellando

Nice re-entry into the warm sound of a tube amp with cinch connection and Sony 7506, update: 05/10/2019: All other systems I've heard since then, some with 5-digit audiophile dream systems, come mine Not too close to Fosi Mini Headphone Amplifiers, the Sony 7506 Fosi DAC or the Edifier powered speakers. Very happy with the purchase!. For the money, it's hard to find anything more acoustically accurate. I replaced the tubes with 5594 USA GE, but acoustically the difference was negotiable. Give them a chance!
