Over-engineered perfection
The development of the UNUM is kindled
by the ambition of producing purest and cleanest transmission of both signals and power, reproducing the essence of the original
signal sources as total as possible.
PURIST, TO THE EXTREME
"all components are attached onto the PEEK circuit board and connected directly to each other without intermediate disturbance, reserving the quality of the original signal."
Nuts and Bolts
It is common to use metal or stainless steel screws and braces in the industry, but we raise a big question. We pay attention to the magnetising effect and eddy current. When a signal or current goes through a metal plate, the electric field will generate a magnetic field within the metal and this potential energy affects back to the signal. In our test this magnetic field generates a blur and cloudy effect to the sound.
​
To further increase rigidity and stability of the whole, we decide to go for Titanium screws, in which the yield and tensile strength is higher than common stainless steel screws. Besides, titanium is more environmentally stable than stainless steel. As a result, amplification is under a much more stable environment.
​
Similarly, for transistors, whenever metal screws are used, it gives a less transparent, pure and direct sound. No metals. Yet, it has to be strong enough to firmly hold the transistors. Even usual plastic screws cannot do, PEEK again is the solution.
​
No details are too small to be missed.
