I bought a "Zero Zone" preamp through Tubes4Hifi that is marketed on ebay and Ali Express as a "CJ clone" circuit. Maybe fake CJ, but a real enough preamp, and I like it...quiet, musical, ample gain.

I use it with a Mytek Liberty, Node 2i, and vinyl theough a MoFi UltraPhono. Works for me.
Moral: plenty to be wary of coming out of China, but some nuggets...
