MC Cartridge: Elliptical; around 0.5mv; track 1.25-1.75; Affordable

To OP, 

Should you decide to get another phono stage, get one with adjustable impedance to give you more flexibility when it comes to choosing which MC cartridge. Reading your post last night, I was thinking of recommending the Hana low output, but it needs at least 400 ohms, whereas the Cambridge Duo has a fixed 100 ohms. The Hana would work with 100 ohms, but would not sound best. Happy listening. 

OP, 
Do you absolutely need a dual-input phono stage? If so, you can also look into the Pro-Ject Tube Box DS2; otherwise, the Tube Box DS.
