Oh I didn't see that about the impedance setting but that was my understanding that it just affected the power output of the preamp, good to have that confirmed. Could a crummy preamp overdrive a power amplifier or adversely affect it in some way?

I'll have to call them and see what they say, I have communicated with Lonnie via email but have been dragging this out because I've want to make sure it's not some basic mistake I am making in my setup, given that this will be my first HT system which I am building more or less from the ground up.
