My Broadest Experience is with Ortofon.
I have heard the Flagship Models and their Trickle Down Technology Models since the Millennium.
There is a family trait where a Sonic is detectable and the variation from one Cart to another is also detectable.
I like a very clean cut Bass Note with no overhang, it has to be perceived as having a decay, this allows my Mid and Upper Mid's to be projected and have a improved presence.
To achieve this Balance, I had a Ortofon Cart' built with the description of my needs guiding the design.
The Built Cart has been compared to other Ortofon Cart's produced over the last 20 Years and I am not wanting another Ortofon at present.
I do have one other Ortofon as a Donor Cart' to go for a rebuild, but there is no rush.
The good thing about Cart's is that many that are sought after are from a range within a Brand, and because of this there is going to be a family trait that can be detected.
If you visit the link I have made available for Juergen, there is a vast range of Cart's that have been used and assessments offered.
