[Elecraft] 6 m reception comparing with KX3

[Johnny Siu]

Hello Group,
 
Apparently, KX3 has extra pre-amp gain in 6m.  Does this mean that KX3 has a better ear in 50Mhz?
 
In other words, unlike K3, KX3 does not require a PR-6 to reach the required sensitivity.  Is my understanding correct?
 
Thanks for advice in advance.

TNX & 73,
