Ken's NEUANCE shelves are an attractive, very affordable, easy-to-use system to isolate CDPs, especially. No change in spectral tilt, but trememdous improvement in clarity and coherence of low-midlevel source components. After the dramatic improvements on an old Rotel I had to get a pair for my EMC-1 (44 lbs) and Aleph P pre (35 lbs). These massively built components may not benefit as dramatically from the Neuane, but then again their resolving abilities should allow perception of even subtle improvements, so I use 'em there, too!
