Interesting!
They certainly have a tight cluster of options for Marantz SR601X models:
SR-6012 refurbished for $749 (1 year warranty)
SR-6013 refurbished for $799 (3 year warranty)
SR-6012 new for $849 (3 year warranty)
Feature-wise, I'm not sure the 6013 offers much over the 6012 (I did not check).
Generally, I'd consider $50 a good price for a 2 year warranty extension and potential resale value of 6013 vs 6012 (just shows as a year newer on used market).
If anyone has serious qualms about buying a refurb, the new 6012 is a nice option.
