Well, I finally swapped in the Nagaoka MP-200 for the Sumiko Moonstone. Wow, it sounded like a veil had been lifted. The 200 is way more dynamic, has a much larger sound stage, with more air and transparency. Detail and textures were improved as was treble without being bright. The Moonstone definitely has rolled off highs in comparison. Bass is punchy, tight and controlled. Midrange is fuller. This TT begs for a higher end cartridge. I am rethinking the Hana ML MK2 and considering the Nagaoka MP-500 or a Clear Audio Concept Virtuoso both MM.
