The Quintet Bronze should have the warmer signature and the black more detail, if they’re similar to the the Cadenza line. Also, the Black has a Shibata stylus. I’ve read that shape is closest to the cutting head’s but also has a comparatively rapid rate of wear. 1000 hour estimate on my Cadenza Bronze as compared to my Dynavector XX-2’s 1500. Speaking of Dynavector, my previous 20X2m was full and punchy and I never lacked for warmth. The Cadenza Bronze is fuller, punchier and way more detailed though. I think meaty is a good descriptor of the Bronze character.
