Schiit Mani or Cambridge duo or Mofi ultraphono for a phono stage.

I like the MoFi - has a mono switch which comes in handy

This is a topic close to my heart. Through the years, I have owned the Cambridge 640p, the JoLiDa 6DJ9, MAGI (NOS tubes and handwired PTP, designed and made by Mark Voigt), and my most recent, the Schiit Mani.I have no experience with the MoFi unit, but here's an A/B review between the Schiit and Mofi on YouTube:https://www.youtube.com/watch?v=O96tQ2Tqa0s

The Cambridge I owned is probably irrelevant because I had it about 12 years ago, the JoLiDa smoked it (and had far better configuration switches and controls). Soundwise, the Voigt units spoiled me with front panel configurability, NOS tube magic, incredible dynamic range, truth of timbre, fully natural recording venue ambiance.

But it was the Schiit Mani that captivated me with its speed, dynamics, organic "feel," bandwidth, totally captivating sonics, and made it easy to forget about the Voigt units. I still remember the Voigts fondly, but some of those NOS tubes died and I couldn't find replacements. At $129 and a 15-day return period, the Schiit Mani is a no-brainer. Mine's staying on my rack right below the turntable and right above my line stage.

Jason (a Schiit founder) over on head-fi just today alluded to a coming "insane" new phono pre-amp - what ever that means.

As for cartridges, I favor HO MM with the Mani, but HOMC sounds and works well, if your line stage has enough gain for your taste.

I'm a pretty big fan of AudioTechnica MM carts. They are linear and musical, and they have a new line, the AT95-VM series, which has a wide array of state-of-the art snap-in replacement stylii: bonded conical, bonded elliptical, nude elliptical, nude MicroLinear, and nude Shibata. 

The only item I have and use regularly is the Mani.
Very very good, better than cds playing thru the Schiit Modi3 Dac. I'm a big jazz fan and this preamp (with Thorens TD203 and Ortofon 2m Blue cart) is simply amazing for me. Great PRaT, bold and tight bass, detail and air. I see no reason to change my analog set up playing thru an el34 tube integrated amp.

The Nagaoka MP500 and Mani combo.

Honestly, if I had to choose one right now I would probably go with the Cambridge Solo since (it's exactly like the Duo, just no MC - and I only have MM, so I can save a few bucks here). Right now the Cambridge is the measurement king for budget Phono preamps and that is worth a lot of points in my book.
