Match Amp to Spendor Preludes - Meridian or Creek

I have a set of Spendor Prelude Speakers. I currently have a Small NAD Integrated Amp that can't drive them.

I am looking at a couple of integrated amps. A used Meridian 551 or a used Creek 5350SE? Which would you recommend as a better match to the Spendors? Whay?

Any thoughts would be appreciated.

Thanks
Marty
