  Hello Paul,
   It is my belief that you would not see any better signal to noise ratio 
with the
Plus-6 amps when used on a three element array.  Just more gain.
The combining losses in the three element array are substantially lower 
which
 keeps the noise figure of the array a lot better than the more lossy 4 and 
8
element controllers.
   The 8 element controllers are significantly improved in SNIF
 (Signal to Noise Improvement Factor) with the exchange of the Plus-6 amps
 whereas the 4-square is improved, but less. I would judge this as a minor
 improvement to the 4-square noticeable only in the quietest times. Likely 
no
improvement at all to a three element.
