TAP1 PRO Standard Version 4PCS 627BP Op Amps Fully Balanced Portable HiFi Headphone Amplifier Electronic Tube Amplifier

Features:
- The electronic tube has second-generation shock absorption technology and is flexibly connected to the PCB board.
- The component architecture of desktop computers is integrated into a small body to achieve HIEND level enjoyment without occupying space. Combined with PSU power supply (optional), it can reach the level of a desktop computer.
- Four channel fully balanced architecture design, supports upgrading to fully discrete Class A, supports single ended upgrade to fully balanced (3.5 output upgrades to 4.4 fully balanced).
- The sunken pin socket technology optimizes the operational amplifier space within a thinner body.
- Supports 4.4 balanced and 3.5 single ended input, 4.4 balanced and 3.5 balanced output, support 3.5 upgrade to full balance with stronger sound quality.
- Function: Supports 10DB high gain and high thrust, supports turning off the electronic tube to use pure transistor mode, and supports electronic tube attenuation.
