Thanks Frogman, for amplifying (đ) your use of the word "dated" relating in particular, to MC cartridges.....
It is here, where I believe we diverge significantly in our preferences and I believe you highlighted in an earlier Post, that your all-tube amplification system may be a factor...?
Looking through the MCs that you've had/have in your system....I can't see many/any that could really be called 'modern' designs so I'm curious as to which 'modern' MCs you refer to when you state...
Imo, excellent modern MC cartridges, are generally more refined sounding and offer better performance at the frequency extremes, the highs in particular.  They do a better job of conveying the natural timbres and texture of instruments without harshness.
My experience is quite the reverse....đ€Â
I find the 'modern' Lyras (Helikon, Titan i, Atlas) to be either coloured (Helikon) or unlistenable, with etched and screeching highs, recessed mids and little depth or realism in my SS system.
I also, like you, had the VDH Grasshopper (aka Symphonic Line) which, whilst I preferred to the Titan i....shared many of its mid to high traits.
The Koetsu Urishi I found decidedly boring whilst the Clearaudio Concerto and Insider Gold were coloured 'warm' in direct contrast to the Lyras.
The Dynavector XV-1s was amongst the best (least flawed) of the 'modern' MCs in my system, but definitely added some tonal colouration to the presentation as well as having a monotonous 'signature' to everything played through it.
The ZYX UNIverse was perhaps the most 'neutral' and least offensive of all the 'modern' MCs I've heard in my system and I lived with it for 8 years (going through two with a third as backup).
It was only when I heard the 'old' LOMCs (and vintage MMs) from the 'Golden Age' of analogue...that I realised just what was missing from the ZYX đ§
The Palladian, I agree.....is easily the best modern LOMC I've heard, but as I described, was designed by Dietrich Brakemeier with the 'sound' of the vintage FR-7f and 7fz in mind.
Like Chakster....I don't see any progress or innovation in cartridge design (MM or MC) over the last 30 years to warrant better performance at the frequency extremes. In fact, most printed FR charts which regularly came with the vintage cartridges...are similar of better than those which can be found for 'modern' ones and we've actually lost some technology (beryllium cantilevers) that we had in the past.
So what can account for our quite opposite 'general' views and preferences on cartridge design and sound...?
Obviously your tube-based system vs my SS one is a significant factor....but in the end, it has to be 'preferences' and individual 'hearing' differences that set us apart.
For instance...you often refer to the sound of 'horn' speakers in a somewhat derogative fashion whereas I like horns and the very best speakers I have heard are the AvantGarde Trios with triple-stacked Basshorns đ€Ż
It's commendable then, that faced with the difference in preferences between us...we are still able to have a meaningful dialogue on cartridge comparisons...đ€Â
