Silk Road is a high end solid state preamp, featuring a fully discrete gain stage with hand matched transistors.
A DC-coupled, capacitor-free signal path yields a phase shift free operation, useful especially with low end rich signal sources. Extremely low distortion enables even intense subsequent equalization without unpleasant artifacts. The gain is divided in 3 stages, thanks to the 3 pos toggle switch and the conductive plastics trim control. This facilitates precise adjustment and eliminates gain jumps. The vibe switch is a complex impedance selector that yields 3 distinctive tones: smooth, present and warped. It helps tailor the character of the preamp to suit the instrument recorded and the microphone used.
For even more tonal variation, the output can be transformer driven or electronically balanced. Both input and output transformers are high quality Cinemag units that impart weight and definition to the sound.
Silk Road is a portable, dual channel unit with an integrated power supply and some added features compared to the Silkworm series 500 module. Due to a higher, dual 24V power supply it’s headroom surpasses that of any series 500 units. Additionally, a 3-position high pass filter can help remove unwanted low end.
This unit has an amazing tonal flexibility that ranges from vintage preamp emulation all the way to modern, pristine realism, and as a result excels on everything thrown at it.
Here’s the Silk Road’s first industry magazine review; Sound On Sound puts the unit through it’s paces (July 2016):
One of the reviewer’s final remarks:
“Surprisingly, I can’t think of many dual-channel solid-state preamps with instrument inputs in a desktop-format, let alone any with discrete transistor gain stages or the tonal versatility of the Silk Road!”
