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 the USABy “designed and built in the USA" 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 in California. Our PCBs are made in California or Nevada, and it all comes together in our Corpus Christi facility.2-Year Warranty, 15-Day Easy ReturnsSYS is covered by a 2-year limited warranty that covers parts and labor.
