How about one of these?:

They are supposed to be pretty clean.

I use one for bi-amp setup.
I have no direct experience with the Schiit Sys but I've had a couple other Schiits including the Freya + and Kara. Both of these can be run in fully passive mode, buffered passive mode, but in my setup I much preferred them in active mode with gain.
The MAIN thing passives are known for is ultimate transparency but IMHO sometimes they sacrifice too much in other areas. They are very cable dependent and system component dependent, more so than when using an active preamp, so short cables and component matching with a passive are much more critical.

The SYS is totally passive and has no effect on the sound when in the circuit. I use one to balance the ARC tube amp playing the mids and highs with a Mc transistor amp for the bass. Changing leads didn't change the sound so far as I could hear. I use this setup for music.

One correction on that passive preamp. It's max output impedance is 2.5k not 5k
