"How do I tone down an amp to not damage the newly purchased speakers?"
That's not a problem. You adjust the gain for each channel using the preamp in your Marantz just like you normally would. The best way to not damage your speakers is to listen to them. You should easily be able to hear if something is straining. If it doesn't sound right, turn it down.
