Pure Class A single-ended tube & MOSFET headphone amp with pre-out

This is our new 2022 updated headphone amplifier, use 2x 6922 / 6DJ8 / 6N1P / 6N2P / ECC88/ ECC188 / ECC288 and all compatibles. The following is the special features of this design

- Zero feedback design, with most open and dynamics sound quality

- Super quiet "hum-free" design, highest signal to noise ratio with darkest background performance

- All component-to-component and point-to-point hand wired

- Pure class A single-ended from input to output

- Single stage tube and single stage MOSFET design, least possible parts with most transparent and micro dynamics

- High quality high precision instrumental grade components

- Tube socket with shield to further enhance S/N performance and prevent microphonic

- Sweet and smooth tube sound with high power MOSFET with super low output impedance, can drive most of headphones to their max. possible loudness.

- Heavy duty solid aluminum chassis for max. shield and durability

- Pre-amplifier output included for possible use this as tube pre-amplifier

- 12V DC input, easily upgrade with our enhanced power supply. High power 12VDC 5A power supply included. Can also power up by any 12V DC 4A or higher current source.
