As I read the numbers the FT-DX101D is not necessarily the top radio.
Here's why:
Noise Floor ---- FT-DX101D -127 dBm Elecraft K3S -135
dBm FLEX 6700 -118 dBm
AGC Threshold ---- FT-DX101D 4.5 uV Elecraft K3S 1.5 uV
FLEX 6700 4.2 uV
100kHz Blocking--- FT-DX101D 147 dB Elecraft K3S 150 dB
FLEX 6700 130 dB
Sensitivity ---- FT-DX101D .60 uV Elecraft K3S .27
uV FLEX 6700 2.0 uV
LO Noise ----- FT-DX101D 154 dBc Elecraft K3S 144
dBc FLEX 6700 145 dBc
Dynamic Range wide spaced --- FT-DX1010D 110 dB Elecraft K3S
107 dB FLEX 99 dB
So you see, one needs to look at ALL the numbers, not just the ranking,
based on Dynamic Range narrow spaced.
All numbers from Sherwood Engineering 3/7/2022 Receiver test data.

Scott,
??? Well, yes: The "numbers" say one thing (or several things!), but,
like I said, I'm in love with Elecraft... So, yes, I'm prejudiced! Of
course the "top radio (FT-DX101D)" is somewhat more expensive then the
6400, and does seem to have some nice whistles and bells. Who knows?
Maybe I'll do a switch to Yaesu... {'-)

Actually, the Yaesu FTDX101D/MP has the best receiver numbers on
Sherwood's list. That doesn't mean that it's the best radio for you,
but the Flex and the K4 aren't "far and away" better receivers than
anything else in the amateur market. Ironically, Rob seems to really
like Icoms...
