Mitch I asked that same question.
Checked the manuals and they are the same. The output stages are the same and the schematics look the same. I do not have TT so you need to ask Rick (Mac Temptation) about the sonics.
C1000 has more "Kwel" visual presentation (3D glass, metal remote, branding on the top of components). Packaging is also a bit different you get the components wrapped in a valet type of material once you get it out of of the outstanding boxed set.
