I'm not sure whose post you are referring to. There's been complete radio silence from Fractal regarding why this particular preamp was not modeled, in light of the overwhelming number of requests. I'm making a huge assumption, but I think its because they simply don't think it sounds good enough, or unique enough compared to the current roster of amp models. I don't think there are any technical limitations to model it. The big three MIDI preamps back in the day were ADA MP-1, Marshall JMP-1, and Mesa Triaxis. We already have the Marshall and the Mesa.
