Frequently Asked Questions
The '2' version has improved attenuators and a black front panel, but the core SSI2144 filter circuit remains the same; the sound is very similar.
While you *can* use it as a preamp, the input attenuator limits its gain range, so it's best suited for subtle coloration rather than significant amplification.
The SSI2144 is a legitimate, originally designed chip, albeit less common than some others. It offers a distinct flavor compared to other filter designs.
