Dynavector XX-2 MK2 vs Shelter 901 MK2


I have upgraded my Clearaudio Concept to Performance DC with Concerto V2 cartridge but I find it sounding bright with vocal sibilance on some of my vinyl collection. Set my phono preamp to 25ohm to tame the brightness. I triple check all my alignment, tried different positions to no avail. I am using the Clearaudio Alignment gauge which I tried the Clearaudio recommended and the IEC standard. Seems like I hit the dead end so I decided to try a much warmer cartridge either the Dynavector XX-2 MK2 or the Shelter 900 MK2. I listen to all genre except classical but mostly rock.

If you have experience on either or even better, on both cartridge please advise.

Have you played with VTA?

I think the Dynavector XX-2 MK2 is one of the best $2K cartridge around. It does everything well, but excels at rock.
I never thought the Dynevector XX-2 MK2 was considered a warm cartridge. I am curious to learn what others say. I don't know what has changed with the new editions. I like Dynevectors a lot and think most of the better models would be great with rock, but personal preferences are really just that, preferences.
I agree with both Brf and Mechans. The Dynavector XX-2 mk II is an excellent rock cartridge, very dynamic and powerful, yet no too bright. However, I would not say it is warm either. I haven't heard the Shelter.

A cartridge in that price range which could be considered a bit warmer sounding that the Dynavector would be the Ortofon Cadenza Bronze or Sumiko Celebration II.
A wood body Benz or Koetsu Black would be warmer still.
