Hi-Fi Hybrid Tube Amplifier: Experience the warmth of vacuum tubes and the precision of transistors. A6 blends 6P15 and 6N1 tubes to deliver lush harmonics, wide soundstage, and lifelike dynamics for immersive sound enjoyment.

Universal Inputs for All Sources: The A6 offers versatility with Bluetooth 5.3, Optical, Coaxial, dual RCA inputs, plus a built-in USB player supporting lossless formats like FLAC, APE, and WAV. Connect easily to CD players, PCs, TVs, tablets, and more.

Flexible Output Options: Connect an active subwoofer via PRE-OUT to build a 2.1 system or link another amplifier for a multi-channel setup. For private listening, plug in headphones to enjoy rich tube-driven sound. Whether room-filling or intimate, A6 adapts to your needs.

Powerful Class AB Amplification: With max 25W per channel, A6 delivers punchy, detailed sound that rivals 100W×2 Class D amps in real-world use. It drives bookshelf and floorstanding speakers with ease, revealing rich textures and lifelike musical dynamics.

Retro Design with Modern Touch: Fine-tune tone with dedicated knobs and switch inputs with ease. Glowing tubes, dynamic VU meter, and brushed aluminum finish evoke vintage charm—all in a design that looks as good as it sounds.

Q: What tubes does the A6 use, and are they replaceable?
A: A6 adopts 6P15 and 6N1 tubes. 6P15 can be replaced with 6CH6, 12BY7, or EL180; 6N1 can be replaced with 6Н1П , 6AQ8, AA61, or ECC40/82. Q: Is headphone output prioritized when plugged in? A: Yes, when you plug in your headphones, the A6 automatically switches to headphone output. The speaker output and PRE-OUT will be disabled. Q: Do the volume and tone adjustment apply to both the PRE-OUT and speaker outputs?
A: Yes. Q: What is the Bluetooth name? A: When Bluetooth mode is selected, the A6 will show up as “A6” in your phone or computer’s Bluetooth list. Q: Is there an indicator for a successful Bluetooth connection? A: Yes, the front-panel indicator will be solid blue when the Bluetooth connection is successful. A flashing blue light indicates that the connection has not been established. Q: Is the playback control knob functional in all input modes?
A: No, it's only functional in USB and Bluetooth input modes. Q: Why does the VU meter needle hardly move? A: It's normal that VU meter needle moves more noticeably at higher volumes. At lower volumes, it may not move as much. Please try increasing the volume for more visible needle activity. Parameters
