The *difference* between the DMC 12 and the DMC 20 *is* the split passive RIAA *and* a change in the board layout and materials... iirc the 20 used a foamed polypropylene pcb material. The gain stages were otherwise identical.
Neither of them used any ribbon connectors.
As I mentioned I have no idea what is in the DMC 30, and no idea what if anything they have done to these models in any newer versions.
All of them are very clean, and low distortion designs. Imho, far better than a majority of solid state preamps.
Robertd made a comment in which he somehow misinterpreted what I wrote earlier. "...According to Bear, I shouldn't really expect much change." I'm not sure what he was thinking about, but I don't think that's what I was talking about.
Anyhow, if I had to own a commercial solid state preamp, Spectral's would be on my list.They are clearly a step or two up from the average stuff being sold.
