A Black Box to Solve Everything

Tubes vs. solid state?? There's a thread out right now about this exact question (there always is), but I didn't want to take it off subject. So my question is; is there a device that could go between the preamp and amp that has variable harmonic distortion capabilities? I know there are tube buffers, but they are not really addressing the point because they use line level signals and don't have the distortion of a good 300B tube being pushed beyond its limits. My thinking is that of a black box with switches and knobs to adjust harmonic distortion to mimic different tube types. It would also have to have a bypass switch so we could readily and quickly A/B the thing. Any ideas?

I have a BSG QOL Signal Completion processor in my system and I use it most of the time. It is not adjustable and I would not describe it as adding any sort of tube distortion. It affects the phase information in the signal and adds depth and focuses the imaging. I suppose one could describe these effects as tube virtues but I've never heard any piece of tube gear that has such a dramatic impact on the signal. I also have a Yaqin tube buffer which produces a very subtle difference - nothing close to what the QOL provides.

BTW, I've experimented with several signal processors and the QOL is the only one I use. It adds a very nice effect.
