Yes, attenuation at the amplifier is a very good idea (or buying a preamp with a realistic design to begin with).
The amount of padding will depend a little bit on how sensitive the speakers are and how sensitive the amplifier is.
The 85K/10K combo will provide 20dB of padding. You will typically see morel like 8.5K/1K, which is more immune to the resistor installed across the RCA jack in the amplifier, and less likely to pick up noise when used.
