Well, since you haven't received any pertinent replies, I'll throw my
two cents' worth in.
I have three older P2K non-sound SW9/1200's. They run as well as any
P2K loco, which is to say somewhat better than a typical Athearn but not
as well as an Atlas.
Can't comment on the sound, except to note that they use QSI sound
systems which seem to have a reputation for being good-sounding current
