I bought this little $49 passive preamplifier to use in a CD-only garage stereo system.
For fun I plugged it between the Schiit Mani phono preamp and the Aleph J amplifier, using the cheaper of my turntables, the Dual CS5000 as source. The SYS sounds really nice. There is that slight lack of drive I've heard before with passive preamps but detail and transparency is extremely 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 that will have to wait for another day.
For the price, it's a steal and would work wonders in simple system.
