What phono preamp are you using?

I use a Modwright SWP 9.0 Signature with an upgraded power supply. I think if I were in your shoes, I would get the Modwright PH 9.0 Phono Stage.

I am using an AT ART 9 cartridge, it sounds amazing on my Garrard 401 and Dynavector 501 arm vinyl front end. 

    Good luck, and best regards,
Dan
