Reference one MK-V tube line preamplifier     (Since: Nov 2021)



The Reference One MK-V (Since: Nov 2021) is Audio Experience Reference Grade line preamp. it uses one E88CC at tube input stage to driver EC8010 tube with one Hasimoto line output transformer construct Class A for each channel.

 

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 New MK-V  improved the circuit of amplifier, the sound got full upgrade about 30% than MK-3 Ver2
The T.H.D of MK-V is 0.04%
  1kHz at 2V , The before
MK-3 Ver 2 is 0.05%  1kHz at 2V

The S/N of MK-V is >114dB , The before MK-3 Ver 2 is >113dB.
