With Cart' selection, there is the presentation/sonic character of the Cart' being selected that is quite a important factor to consider.
Cart's can present as Transparent through to have a very noticeable Rich Tone.
With a MC Cart', I lean towards noticeably Transparent and add Tone 'as and when desired'. Platter Mat's, Phon's>SUT configurations, Cables and Speakers are all able to add or remove the presence of a Rich Tone, when understanding how certain permutations of these items in use are assembled.
A Cart' with a Aluminium Cantilever in today knowledge for Cart' design, is using the Metal Armature to add Richness to the Tone, Brands that have a Cart' Range will usually have the Metal Armature to voice the Cart' different to the Boron or Ruby/Sapphire options.
If an individual is sensitive to a Rich Tone being noticeably present, using materials capable of creating such a perception, and one that firther accentuates Richness of Tone in a system, might create a sonic where the presence of Richness becomes a constant distraction when listening.
It is each to their own, I know some who like very noticeable Bloom in the Bass, and some who like to hear a underpinning of the sonic, not too far removed from being Transparent.
Through my own offering of demo's, where creating differences to the influences of a Rich Tone is undertaken during a replay, there are always mixed responses to the impact of the Tone being produced from individuals receiving the demo'. My method's are not always capable of producing the deeper depth for the range of available Tone that certain individuals prefer.
