Don't know JD9/JD9II differences. All use tubes in their circuitry to varying degrees. I believe the Bellari will work with MM or HOMC only and is not adjustable; the Jolida (JD9) is a variable gain MM or MC pre with very flexible loading options.
Both are respected and recommended within the context of what they do and price point.
