I had an R390A and currently have an RX340. I can't comment on the SX-28.
The R390A did very well in it's day. It was one of the most accurate and
stable receivers of its time with excellent mechanical filters. It played
real well on AM, SSB, and CW.
Today's RX340 is much more accurate on frequency readout, much more stable,
and has much sharper filters with better skirt factors. Both receivers have
enough sensitivity to make sensitivity not a factor. The RX340 plays
extremely well with exceptional audio quality on AM, SAM, SSB, and CW. The
SAM (synch AM) was not even thought of when the R390A was designed.

Subject: [TenTec] Perspective on RX-340, Collins R390A and Halli. SX-28
> Hi folks -
> Can some one give me a non-technical historical perspective on how these
three receivers would compare if lined up side by side with ABC testing on
the same antenna? The Hallicrafter was early to mid forties; the Collins
early 50's and the RX340 current. Ignoring bells and whistles and operator
conveniences, how different are these receivers in their ability to hear?
Did the Halli and the Collins pick up SSB in the same way a modern receiver
does or were they pre-ssb (or right in the beginning of that technology)? I
don't know if any of you have the knowledge to cover all those "periods" but
I would love to get a better perspective on the development our ability to
listen. Thanks.
