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!

The Parasound Z Pre is a very nice pre in your price range when used, with tone controls.
The loki is just a tone control I think, not a preamp. As I said in the other thread your system needs a better cartridge and maybe some loudspeaker positioning changes rather than new electronics or equalizers. Electronics to cure or change the sound is sort of a last resort after you have tried everything else.

BTW: What loudspeakers are you using?
