The screengrab pictures are sure pretty. *Any idea how they satck up

I think it is trying to compete with the Perseus. Don't appear to be
any prototypes floating around. The earlier WR-G313e has lower dynamic
range but the numbers on this model look promising. Hopefully QST or
Sherwood Engineering will test one when they are in production and
verify the numbers.

I volunteer to test one!

As far as numbers go (at the Sherwood site), the Elecraft looks plenty
hard to beat. I wish they just made a stand-alone RX. I'd even buy
the kit, and hopefully not screw it up!

I think that the coming AOR AR-7070 will be a good receiver IF they
build it with quality parts. The 7030 was an excellent receiver, but
it only worked IF you got a good encoder and IF the buttons made
contact.

That is where SDR's have the advantage. A lot of the cost is saved in
a mass produced computer that is supplied by the customer. Fewer
hardware filters and mechanical controls. Most of the expensive stuff
is dealt with in the software.

Maybe you have seen this link. It has a picture of the inside of the
7070 receiver:
