DA1 Analog HiFi Pure Digital Power Amplifier Blutooth5.4 Subwoofer Better than TPA3255

Introduction:
- DA1 has a remarkable effect when used to push flat earphones or high impedance dynamic coils (low impedance headphones may have background noise), especially for HIFIMAN edition and BEYERDYNAMIC T1 (600 ohms) headphones. DA1's EQ can be used to lower the high-frequency and increase the mid frequency thickness. Please pair it with a banana head to XLR adapter (not included), otherwise there may be background noise.
- The DA1 combined amplifier uses a rare pure digital mode on the market (omitting the decoding DAC link), and can enjoy the purest sound quality performance using only the simplest amplification modes such as coaxial or fiber optic, USB, etc.
- Professional level 15 segment lossless EQ equalizer: Each segment can be adjusted by ±12db, and you can choose your favorite tone style.
- Specially designed pulse absorption circuit brings you a warm listening experience in your memory.
- EQ attenuation can be used in the low-frequency range (3.5mm subwoofer output is not affected by EQ) to perfectly connect the main box and low-frequency subwoofer, without the annoying phase and sound pressure disorder caused by low-frequency overlap.
- DA1 amplification principle, full digital signal, fundamentally eliminates interference.
- Aluminum alloy integrated molding oxidation process.
