Chak, do you really think an MM phono stage needs the option of 30 ohms loading? Or was that a typo, and you may have meant 30K or 30,000 ohms, which does make sense?
Buy the very best MM phono stage you can afford, but don’t assume cost and quality are proportional. If you succeed in reaching that goal, you may never need to “upgrade” if you purchase a LOMC cartridge, because you can add a SUT or pre-preamp for more gain. To get where you want to be is a process of trial and error for each one of us. No one can tell you what you will like. I’d suggest Sim Audio, Herron, Hageman, K&K units with at least 40db gain or any excellent used unit to save money.
