Terry, I have made a complete set of response spectra from K2 #489 for all
filters and modes using SpectraPRO, which is a high-end professional audio
analysis suite. The results are in much more detail with higher resolution
than SpectroGram provides. 

I will make a similar set after the new crystals are installed and make
available the results of comparisons.

From the look of some of the present responses, I am reminded of the old
Army saying "Any change must be an improvement!"
