Very nice job of comparison, though I think you have the filter
bandwidths incorrect. As far as I recall, the 450 has the Murata
ceramic K15 filter on board (isn't that a 2.4 kHz filter?) and the
optional filter for the 8.8 IF is the YK-88S-1, another 2.4 kHz
bandwidth filter. The TS 850 has a pair of 2.7 filters, the Murata
ceramic K12 and the (not optional) YK-88S1 (note the difference in where
the dash is placed :-) which is a 2.7 kHz filter, unlike the YK-88S-1.
I haven't had my 450 in a few years, but I recall comparing the filters
this way.
I think it has already been noted, but the 850 processor is an RF
processor, really a different animal than the 450 audio processor (and a
whole lot better for "sound").
Thanks for the well thought out comparison.
