Review on 🎧 SUCA Audio Tube-T2 Headphone Amplifier: High-Fidelity Mini Vacuum Tube Amp with Low Ground Noise, RCA & 3.5mm AUX Input, Compatible with 6.35mm to 3.5mm Headphone Jack by Ashley Scott

Totally low power and cannot drive 62 ohm banks. I'm wondering if the x4 op amps (x2 soic8 and x2 dip8) are real 5532? I was only able to get acceptable sound (no digital bass) after using the preamp to increase the input voltage and replacing the x2 detachable op amps. The included tubes are decent if you like a lot of bass and I've supplemented my tube preamp with various tubes. I'm honestly very happy with the result, but it took a lot of work and additional components. I don't think the amp produces itself. If you enjoy crafting, try this, but if you want out-of-the-box quality, choose something else. I use a Nobsound tube preamp and probably should have gone with their hybrid tube amp.
