Yes, getting the audio out of the confines of the bandwidth limited audio deck
of the 390A does help quite a bit. I have to agree the Super Pro is much much
better when it comes to "listening quality", the SP-400 even more so. 
I foolishly
sold the one I had and only have an SP-600 (actually 3 of them )

The SP-660, is that similar to the SP-666 which only picked up rap, heavy metal
and 24 hour pro wrestling stations??? heehee.
