Phono Preamp Selection

I have no idea of which Phono Preamp I should purchase.  I read the reviews from Audio Science and the author provides testing criteria and results for Phono Preamps. I do not have a awesome system - rather it is just a nice system. I reviewed (Pro-ject Phono Box DC MM/MC  / Cambridge Audio Duo / IFI Zen / Schitt Skoll ). My turntable is a MoFi with a Hana MC Cartridge. 500.00 is my budget as I am just a listener of old vintage records.  My amp is a Denon and my speakers are bookshelf Triangle(s). Appreciate your time and responses.
