This is our 2nd top-most best sounding all vacuum tube pre-amplifier with RCA and XLR balanced inputs and outputs with sonic performance that easily out-perform preamps in the market for almost any price range.
We employ the organic way of designing and manufacturing that has zero negative feedback, no circuit board for tube sections, hand-wired component to components and point to point, Lots of oil capacitors, NOS carbon composite resistors , and high grade ultra heavy-duty transformer and power filter capacitors. This unit is hand-built with no compromise in component quality, very carefully fine tuned for tonal balance, resolution, sound quality, air and soundstage for a pure effortless delivery. All the good sounding options have been integrated into this very special design which almost none of other manufacturers can come even close to.


The end result of our no compromise design and execution is articulation and punch in the bass section with exception of elasticity and tenderness, sweetness and liquidity in the midrange with syrup-like feeling but not sticky, super silkiness and openness in the high frequencies without boundary. 
Because we could not find an ultra high performance remote volume pot, we built our own 100 micro-step remote controllable volume control non-contact, non-semiconductor super high grade volume pot with proprietary software. The volume pot can select between "DUAL VOLUME" mode or "VOLUME + BALANCE" mode by the toggle switch in front panel, the music signal passes thru no switch contact point and no solid-state devices, extreme pure and transparent sound.

The power supply section uses two super rectifier tube 872A to form an organic full wave rectifier , along with a T/D switch to be able to add the touch of diodes when needed. There is 5/10V rectifier filament voltage selection, so even 845 , 805 and 211 can be used in this unit . Pure tube regulators with not a single solid-state device ensure most purest and natural but well controlled full range performance.

A big choke can be selected as a presence or bypass for different pace of music regeneration, Hi / Lo gain setting selection for high / low gain power amplifier matching.

Super low output impedance drive circuit included , easily drive over 10 power amplifiers without any audible degradation, and give out super good bass punch and tenderness.
