The Real Line MK-V line preamplifier.

The Real Line MK-V Preamplifier.
Flagship grade Line preamplifier.

The Real Line MK-V is Audio Experience Flagship Grade line preamp. It 's circuit is new design . it uses one ECC82 tube at input stage to driver NOS Siemens EC8010 gold pin tube with Hashimoto special grade line-output transformer construct Class A for each channel.

The Real Line MK-V uses two EZ81(or EZ80) rectifiers tubes, a high-efficiency solid-stet voltage regulator, an EZ81 (orEZ80) tube for current regulation, and two Hashimoto chokes for each channel's HV B+ power supply. Also it use the external power supply get highest S/N, the power supply is dual mono design.

The Real Line MK-V preamplifier features a newly designed amplifier circuit, equipped with one ECC82 tube and one EC8010 tube per channel. This, combined with a special-grade Hashimoto line-output transformer (which operates at twice the working current of Hashimoto standard version line-output transformers), ensures that the Real Line MK-V achieves lower distortion than previous versions of The Real Line and Reference-X line preamps. With a 2V output and a 600-ohm load, bass distortion at 40Hz is a mere 0.09%, while distortion at 20Hz is 2.5 times lower than previous versions of The Real Line and Reference-X.
The Real Line MK-V's sound quality is significantly superior to previous versions of the Real Line and Reference-X, and the difference is easily discernible (in terms of spatial feeling and bass definition).
