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.

It sounds like your cartridge is new. Let it live for a month or 2 before tossing it. Remember that any adjustment on your arm will affect all the other adjustments ....they have to be rechecked and modified. Your description sounds like an adjustment error, not a cartridge fault.
Stringreen,

That is what I thought before. Did took pictures and videos of all my adjustments and sent it to Musical Surrounding. I wanted to see if there was something I missed. They said everything looks spot on that's why I got my replacement. Realignment of cartridge is done everytime the arm is raised or lowered. Will the vocal sibilance disappear as the cartridge gets older?
Yes I did. Mike is an awesome dude. He is the one who assisted me on this. He said everything checked out so he replaced my cartridge.
