My experience with direct sampling radios (ANAN-100D & Flex 6500 in the
shack alongside my K3s/P3) is that their front ends are plenty robust
enough for contesting and low band dx'ing.  N5AC made some interesting
comments on the topic:

Since the 7300 uses direct sampling, it will have the same blocking dynamic
range (BDR) problem as other radios in this class, especially multi-signal
situations such as contesting. I also doubt it will beat the KX3 in
close-spaced dynamic range, unless they used a very exotic, very expensive
A-to-D converter. (Note that the only way the Flex 6700 series can achieve
good close-in dynamic range is by turning on the preamp. This overcomes the
very poor preamp-off MDS, but at an even greater cost in BDR.)
