[Elecraft] K3: 2.7 vs 2.8 Filters Audio Impressions

[list1]

I have read in the archives about the slope, bandwidth and IMD differences
in these filters.

But wondering if one is noticeably better than the other at making the LSB
and USB received audio sounding similar.  Also wondering if the transmitted
audio sounds significantly better with using one of these over the other.

If everything is about equal I'd definitely go with the cheaper 5 pole
filters.
