I am using Systemdek turntable with Denon DL-103 moving coil cartridge mounted on Rega RB300 tonearm. The signal goes into a step-up transformer (SUT) and then into Pro-Ject Phono Box USB V MM stage. I was wondering if replacing Pro-Ject Phono Box USB V with Emotiva XPS-1 would improve the sound quality? Has anyone tried these two phono preamps?
