Since the load sets damping of the coil, it will surely impact the sound. I would guess a higher impedance load would tend to increase output at the stylus resonance and a lower impedance load would decrease it, but that's just a guess. Might make a little more bass with higher impedance and a little less bass with lower impedance. Probably change the overall output level too.
The standard load is 47KΩ and most phono stage amps have this across the input line. Did you remove that resistor or did you add 100KΩ across the line, making total impedance 32KΩ? I'm wondering if the idea is to reduce damping by replacing the 47KΩ load with a 100KΩ load, or if it's to increase damping by adding more shunt resistance, lowering the load to 32KΩ.
