Mulveling, I have not heard the Cadenza Bronze but by all accounts it is a fine, essentially neutral, cartridge with a dash of warmth. If the Bronze seems ideal to you in your system, then perhaps the Black would be less ideal.
I didn't found the Jubilee "slightly bright/analytical" - in fact I thought the Jubilee was slightly reticent in the highs though quite well balanced overall. The Black has more clarity and energy in the highs (more like the A90) but never 'bright'. Note that I've used Harbeth speakers - 3 different models - for the past 8 years and they have a rather smooth top end balance.
I find the Black to sound quite robust and realistic with acoustic instruments and voice - which is important to me - and I thought the Jubilee was similar though without the same overall clarity/transparency and liveliness.
In a nutshell, if you're expecting more warmth from the Black vs the Jubilee I don't think you'll find it.
