modified LPB (linear power boster)

I noticed on the beavis audio website that on the "booster: how it works" page, the schematic shows a value of 430k/43k for R1 and R2 respectively:

But on the schematic for the fuzzlab jr., Dano has changed the values to 1M/100K for R1 and R2 (listed as "R3" in the fuzzlab jr. schematic):

What is the benefit of this change?  R1 and R2 are still dividing the voltage in the same ratio, but does this yield more/less output?  lower noise?

I believe it raises the impedance.
