For $100 more for the Pro-Ject Debut Carbon EVO especially if you are upgrading to a Marantz amp.
Fluance RT82 is a good value at $300 or RT85 if you must spend the full $500.
If the Onkyo does not have a phono input or you want a better one than what is built into the Onkyo then connect a Pluto 2 $99 to one of the standard line level inputs.
