Bob, could you define what you mean by improved performance a bit?   My 
only complaint in using the GSB-1 with my GPR-90 is that the audio level 
is quite a bit lower when going through the adapter than straight out of 
the GPR-90.  I just assumed this was something in the audio chain of the 
GSB-1, which I've never evened opened the cabinet on, but maybe I should 
look at those switches  instead.   Did you notice an improvement in 
sensitivity, audio, or what?  (I'm using the common connection to the 
TMC speaker as per the manual, by the way).

This combination is really great in my opinion, albeit hard to come by.
