  Lawrence,

    I have many receivers, RA-1792, ICR-75 and Perseus included, among others.
Should I be forced to depart from all except one, the one that will stay is the Perseus.
Granted, it needs some mentality shifting as far as the operating procedures are concerned. You don't have anymore a 
solid  and reassuring heavy tuning wheel in your hand, to slowly turn in search of that elusive whispering, you will do 
the search visually on the waterfall, but which other receiver offers you a continuously variable IF bandwidth ranging 
from let's say 25 Hz to 12 kHz ? A complete view of what is happening in a range of 400 kHz ? A point-and-click tuning 
on the signal that has just appeared inside those 400 kHz ? To not speak of a BDR of 125 dB. Look here :

Though Nico IN3NWV (the designer and producer of Perseus) is one of my good friends, I have no commercial interests in 
this product, so my words are those of a satisfied customer.
