SYS stands for "switch your, er...schtuff." Sys is a simple, 2-input passive preamp. No electronics. No power. No distortion. Just a 2-way switch and a potentiometer.

Huh? Why would you want such a thing? Well, if you've ever wanted to use one of our DACs with powered monitors, Sys puts the volume control right at hand. Same goes for using two sources with one of our headphone amps—use Sys to switch between a DAC and a phono preamp, for example.

And, you don't have to use Sys with our gear at all. It's a simple, high-quality, passive preamp that works with pretty much any line-level source.
Designed and Built in California
By “designed and built in California" this is what we mean: the vast majority of the total production cost of SYS—chassis, boards, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. You get the picture.
