Musicnote MU22 MKII Fever‑Grade Vacuum Tube DAC Dual ES9038Pro Chip High‑End Hi‑Fi Audio Decoder For Audiophile System

MU22 MKII Vacuum Tube Decoder DAC Bluetooth DAC Audio Decoder Optical Coaxial Digital Balance With Dual ES9038Pro Chip

The high-end MU22 decoder for pure tone uses the ES9038Pro decoding chip. Imported MURATA audio dedicated digital output isolation transformer ensures the integrity of digital signal input, and gold-plated temperature compensated crystal oscillator makes the clock more stable and accurate. The red German WIMA capacitor has better audio effects. Original Japanese Nichicon gold and green high-end audio capacitors with lower loss angle, higher stability, and filtering effect.

MU22 comes with an IIS output interface. It can be directly connected to a pure turntable for PCM signal, achieving good results.

When used in conjunction with the pure tone MU21 or MU23 turntable, this decoder provides better sound extension between high and low frequencies. When listening to symphonies, the dynamics are large, and the vocals are full and sweet, with a strong analog flavor.

Product Features

USB uses XMOS solution, PCM supports up to 768KM, and DSD supports up to DSD512.

Use the high-end ES9038Pro D/A chip from ESS Corporation in the United States.

The Bluetooth chip is SR8675 chip, supporting LDAC, APTX/HD, SBC, AAC.

Two power transformers are used, one for digital circuits and one for analog circuits, which do not interfere with each other.

Use 4 high-quality RCA 6CL8 electronic tubes from the United States as the output stage, with 1 tube for each signal.
