Output stage use the super powerful KT150 (can also use VT52 / CV1052 / 6G6 / 6V6 / 6K6 / 6Y6 / 6F6 / 6L6 / 6550 / KT66 / KT77 / KT88 / KT99 / KT100 / EL34 / 5881 / 6CA7...etc direct plug-n-play ), which give superb dynamics sound with extremely good bass control .

All tube section built with point-to-point and component-to-component hand wiring technique to ensure max. transparency and natural tonal quality. Also equipped with filter choke for further musicality and smoothness enhancement, selectible with a selector for different music preferences. Constant current amplification ensure most stable sound stage with super high resolution. Our newest MDE (micro-dynamics extraction) circuit already included in this design.

This is the second model of our Reference series of pre-amplifiers, which have no compromise in build quaility. All solid aluminum chassis. High headroom power transformer which is good enough to power up a push-pull amplifier, give exceptional reliability and stability as well as easiness of the sound with hanging in the air density. Our pre-amp designs are well know as giant killer. We strongly believe this pre-amp can easily surpass the sonic performance of competitors US$30,000-$60,000 offerings.

Non-feedback pure tube hand-wired ORGANIC design with very open , smooth and sweet tonal quality. Those big output power tubes give exceptional richness and texture as well as super high density sound to regenerate the real live performance soundstage, which is never be reachable for products built with those smaller tubes like 6DJ8 / 12AX7 ...etc, no matter how much price they asked for.
