This is our top-most best sounding all vacuum tube pre-amplifier with RCA and XLR balanced inputs and outputs with sonic performance that easily out-perform pre-amps in the market for almost any price range.
We employ the organic way of designing and manufacturing that has zero negative feeback, 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 has been integrated into this very special design which almost none of other manufacturer can come even close.
The end result of our no compromise design and execution is articulation and punch in the bass section with exception 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, so 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 pass thru no switch contact point and no solid-state devices, extreme pure and transparent sound.
The power supply section use two super rectifier tube 872A to form an organic full wave rectifier , come along with a T/D switch to be able to add the touch of diodes when needs. There are 5/10V rectifier filament voltage selection, so even 845 , 805 and 211 can be use in this unit . Pure tube regulator with not a single solid-state device ensure most puriest and natural but well controlled full range performance.
A big choke can be selected as 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 amplifier without any audible degrade, and give out super good bass punch and tenderness.
