[Elecraft] Raspy audio from K2 - conclusion

Well, despite not thinking I'd have time to correct my K2 raspy audio 
until after the holidays, I managed to squeeze in a little time early 
this morning and here's what I discovered:

1)  There is probably nothing wrong with the K2 or the KSB2 board, as 
far as wiring is concerned.

2) Don (W3FPR) asked me a few questions, MOST of which I answered "yes" 
to.  For example, my LSB and USB did sound similar (but raspy).  The 
carrier was balanced well.  The two things I DIDN'T do were adjusting 
the LSB and USB BF1 values for best transmitted signal quality. I guess 
those little check boxes next to the instructions are important after 
all (hi).  The one remaining question I have is the following:

The instructions for optimizing the BFOs say you can move the BFO as 
much as +/- 200 Hz from the frequencies in Table 3.  Moving them about 
100 Hz removed the raspiness,  but I had to move them about 350 Hz total 
before I considered the signal optimum.  Is this setting OK or should I 
back down to around 200 Hz?

Thanks to all for the suggestions on this little problem and 73's,
