The Schiit SYS doesn't add color to the sound, but it can create more authenticity. A passive preamp isn't the right choice in every situation. If you place it between a high impedance source and a low impedance amplifier, you can overwhelm the source's ability to drive audio signals without experiencing adverse effects. You'll notice.. By "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.
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.. Schiit SYS Review. Jay's Take. Sys Manual. Up to 5 Year Warranty 15-Day Money-Back Guarantee Designed and Built in USA;. The SYS sounds really nice. There is that slight lack of drive I've heard before with passive preamps but detail and transparency is quite good. None of that (minor) JFET darkness of the Classe either. I should try the Schiit Mani/SYS combination out with my Thorens TD309 but I'll have to wait until some winter laziness wears off.
