Hmmm...I know of two, but can't speak for either. The Ah!Tjoeb from www.upscaleaudio.com or the Norh CD-1 from www.norh.com The norh is built by the same Thai factory that produces products for Cal Audio Labs, and I hear that it's very much like the Cal Sigma/Delta parts-wise. People rave about both. The Norh should technically be better (it was designed, not modified like the Tjoeb), but you never know.
