You'll get more answers in the Analog forum. In the meantime, what's your budget? The HOMC is sort of a redheaded stepchild given that it's output is too low for a regular MM/MI output and too high for a typical LOMC. Therefore I recommend something that's highly configurable such as the Musical Surroundings Phonomena II or the Jolida JD9A.
I upgraded from the Cambridge 640P to the Jolida and it's worlds better. Not only that, there are several settings for sensitivity, capacitance (for MM), impedance (for MC), and even two different output levels. It also has a whopping big power supply compared to the wall wart models and it's easily tweakable. I replaced the OEM 12AX7 tubes with NOS 5751 mil-spec Sylvanias, and on some models you can replace the standard $4 op-amps with $20 Burr-Browns. I plan to replace my op-amps in the next week or so. Word is that the op-amps make for a bigger improvement than the tubes (which are used to buffer, not for gain).
Whatever, the unit out of the box is an order of magnitude better than the 640P and it's only $450 list.
