Phono Cartridge - From Jeans & T-Shirt to a Suit

Some argue that the cartridge is the least important component of the trio: turntable, arm, cartridge.
There is something about it. Experiment in my home with a friend who brought a relatively simple turntable with a relatively expensive cartridge, my good turntable (LP-12)  won with a relatively inexpensive cartridge. 
Apparently this experience, plus a hearty amount of like-minded friends from around the net led to the absurd/outrageous situation which the temporary cartridge  (cheap) I was putting (Ortofon MC-10), left for a several years. Then I heard less and less records, and more Digital. Something's wrong. A new cartridge is needed!

Cheap and expensive are not necessarily relevant in many situations in our audiophile field, but for the matter of cartridges, it seems that the situation is slightly different.
Except for special cases, a cartridge costs 500$ probably plays less well than a cartridge costs 1500$ and the latter probably plays less well than a cartridge costs 5000$, of course, the same system and the same conditions. But there is a point, especially when the retail prices skyrocketing, which all cartridges perform very good, in most of the parameters, and then it's just a matter of personal taste.

Judging by this forum, my system, based Naim with Linn LP-12, "should" get a cartridge like Linn Kandid or Dynavector XV-1s / t. I heard these three cartridges, and they are all excellent and fit.

However I wanted something a bit different also beyond accuracy and detail and resolution and naturalness.

When I visited last exhibition in Munich I heard a variety of cartridges, some of them I loved and some I hated, I'd probably like some in other situations, on another systems. This issue of isolation system components, while listening to a system one-time, is not trivial, and I try not to do this, if at all.
In Nagra's room a special cartridge was playing, ZYX Omega Premium, with the least expensive system series of Nagra and Wilson speakers.
This is the room where I sat the longest, I went back twice, day after day, and I listened to music I brought which I know well.
We heard a turntable, a CD player and even a tape recorder. After listening to the three sources, I realized, more or less, the 'direction' of the system, and the turntable  played much better than the two other sources. I was Immediately suspected the cartridge.

The importer of ZYX in my country demonstrated me a relatively inexpensive cartridge of ZYX (called R100) on my system.
The result was phenomenal, but it lake the very low area and extra resolution as I look forward to.
After much reading on ZYX across the network in general, and on the Omega Premium in particular, I decided to order it.

After a month of waiting, the dealer came and installed it.
The installation was complete, he went, and I started putting records.
Another record and another record for hours, it's always a good sign that something good is happening on the system.
Records which I couldn't suffer; Shrill, sharp, unpleasant, suddenly I can hear, I can enjoy them.

And yes, I have this special atmosphere which I heard in Munich at Nagra's room, it comes from the cartridge.
There are some extra details from the recordings, not artificial, more lively singers, instruments.
No need to say much about those parameters: resolution, natural, etc. because the cartridge excels in each and every one of them.

If I need to point out the strengths of this cartridge, which is also a weak point of some of the recordings, it is dynamic.
Strengthens and weak transitions never sounded so, not objectively / illustrative, but much more realistic.
Dark sound, intelligent, quick but not too wooly bass, accurate and natural, rhythmic, high and mid which the previous cartridge could only dream about.
All my fears of buying an esoteric cartridge at such a high price (4700£), evaporated.

Then it disappeared. After two days. The magic is gone.
What happened? Nothing has changed.
I consulted with a friend who has a Dynavector XV-1t, the most expensive, and he said that it was so also for him. At first, enthusiasm, everything sounds fantastic, and after that, a very large drop occurs and after then it improved, but I have to wait, and play dozens of hours with the new cartridge.
I was surprised. I was sure that it should be a linear improvement.
Now it's two months later and it is indeed improving.
I now hear a lot of records, purchase records, clear records and back to enjoy the analog sound.

Miki.
