[Boatanchors] Best 1940's Receiver

[Keith Densmore]

Greetings,
Over the years I have had the privilege of owning 4 AR88 (and variants)
receivers. The best of these was the CR-91A variant which had a built in S
meter and crystal phasing.
I have always considered the AR88 to be the pinnacle of receiver design
from that era. But now I am wondering if I have missed something. I am
looking at the specs for a Hammurlund SP-400 and a navy RBB, two receivers
I have never owned.
Would like an opinion as to what is best from those who have owned all.
Sensitivity, selectivity, stability. Ease of tuning and audio quality.
Thanks, 73,
