Product Description
HiFi Bluetooth 5.0 Tube Preamp Headphone Amp DAC and Stereo Receiver
There are some output signal insufficient audio source or inputting low sensitive amplifier and active speakers,resulting in not fully play the sound equipment effects.
Preamplifier can filter out the common sound source of digital sound, so that the listening feeling more soft.
Tube-03MKII Tube Preamp adopts op amp+tube buffer tone,Bluetooth 5.0 audio receiving function and headphone amplifier, that can drive conventional headphone, match amplifiers, active speakers and other devices to improve the sound effect .
You can control the volume and bass&treble independently,according your preference.
Replaceable Tube
Adopts GE5654 tube,it can make the sound more sweet and nature.Audiophile can replace with different tube according to personal preference.Replaceable tube model:6K4，654 /6J1 etc,.
Wide Compability
It can be compatible with multiple audio source equipment,such as smartphone/Laptop/CD/DVD player and so on.And input you can connect active speakers and headphones.
Replaceable OP Amp
Adopts OP amp IC OPA1656IDR,you can replace with different OP Amp IC according to personal preference to improve the effect of headphone amplifier.Replaceable OP amp IC：AD827JN / MUSE02.
Anti-interference
Adopts independent power design,so that the audio and power completely separated to reduce interference, enhance the signal and improve the sound quality.
Relay Switching Signal
Adopts relay switching signal, which can automatically switch and directly affect the stability of signal system, better than common analog switching.
BC Coupling Capacitance
PCB board adopts black immersion gold craft and tube-03MKII adopts advanced component and BC coupling capacitance to provide audio signal channel,so as to minimize the audio signal loss.
You can use in living room,bedroom,study room,coffee shop,bar and other places.
