Upgrade from NAD C558

I went from a VPI hw19 Mark 4 down to a NAD c558 when I downsized. Oddly enough in between I had a Rega RP3 which I really didn't like at all despite its accolades. Anyhow, I run both MC and mm cartridges and looking for something new or used under a thousand that would be an upgrade in terms of stability, vibration and tonality.
