Reference one MK3 tube line preamplifier Version 2     (Since: Jan 2021)

The Reference One MK3 Version 2 (Since: Jan 2021) is Audio Experience Reference Grade line preamp. it uses one 6DJ8 at tube input stage to driver 6C45 tube with one Hasimoto line output transformer construct Class A for each channel. This design is from our Flagship grade preamplifier THE REAL. 


The Reference One 's application of a highly efficient solid-state voltage regulator with EZ81 Tube for current regulator and Hasimoto choke in the HVB+ power supply . Also it use the external power supply get highest S/N, the power supply is dual mono design.


The Version 2 improved the circuit of amplifier, the sound got full upgrade about 30%. 
The T.H.D of Version 2 is 0.04%
  1kHz at 1V , The before Version 1.8 is 0.15%  1kHz at 1V.

The S/N of Version 2 is >113dB , The before Version 1.8 is >110dB.
