  • Total harmonic distortion: ≤1% (at 35W output, 1KHz)
  • Input sensitivity: ≤300mV

Features three functions and two modes:

Function 1: 5.0 Bluetooth HD reception

Support better Bluetooth APTX-HD format digital audio, can play up to 24Bit/48KHz lossless audio files. Directly transmit music to MS-88 through the Bluetooth function of lossless players, mobile phones, tablets and other devices, bringing users the convenience of wireless input audio sources, and also has a fashionable gameplay experience combining traditional HIFI and trendy digital.

Function 2: USB audio input

MS-88 is equipped with USB digital audio input interface to support computer, digital broadcast, tablet computer and other equipment to transmit audio source though data cable.

Function 3: Pure power amplifier amplification function, can be used with external pre amplifier to play more diverse

Mode 1: UL Super Linear Mode

Mode 2: Three-Pole Mode

Tubes used:

1: The pre amplifier uses an ECC83 or 12AX7 and two Soviet 6H8C vacuum tubes for boost

2: The power amplifier uses four KT88C vacuum tubes for class AB1 push-pull power amplification. Push-pull can reduce the quiescent current of the circuit, reduce distortion and improve output power
