What are the most balanced relatively neutral cartridges at each price level ?

I have little problem with audiophile "sound engineering", by the way, for as long as the essence of the performance is conveyed, but personally I would prefer doing it down the chain not at the source. On the other hand, many esteemed audiophiles use Koetsu and Lyra, so perhaps they are right to start doing it at the source. Still, I am a tape man and my philosophy is sometimes a little different. Difficult to bring out the full colour and vividness of the performance without adding some  colourations, doesn't it ? Koetsu cartridges, better Mullard tubes, some cables..

So do I know how orchestra sounds, and small bands, and vocals etc.

Unfortunately, some tape masters deteriorated and their dubs will no longer be reference, in this case your original pressing record will be reference. And if you can find a successful test pressing..

I got it. It's Ortofon. So, yes, there is an answer to this question. Demagogues and dilettantes don't have answers and even don't understand questions, pros do. Thank you.

You don't compare vinyl to digital, you compare it to master tape dubs. Deck's playback head is your reference "cartridge". Best decks', of course.

Generally speaking, cartridges are very coloured, aren't they ? Added colourations, negative colourations. In this sense they are often the weakest link, no matter how pleasing the sound might be. Koetsu appears to be a fine example of it.
