Preamp for under $400 with tone/bass adjustment?

Hi, I am looking for something so I can adjust bass on recordings i listen to. I have a Rogue Tempest tube amp and a $150 NAD preamp and a Uturn turntable. Does such a preamp exist? Or do I need to have yet another piece of equipment in the mix, like this? https://www.schiit.com/products/loki

Thanks all!
