I have upgraded my Clearaudio Concept to Performance DC with Concerto V2 cartridge but 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.

Hi,
Sure the V2 is broken in?  Max VTF?

Looked at photos of the arm - do you know the effective mass??  Carbon fiber arm tube and magnetic bearings looks a little light for the carts you're considering, but I have no experience with the arm.  I was thinking you might have better results with a higher compliance cart.

Neo,

Yes it's broken in. VTF is at 2.8 as manufacturer recommended. I forgot to mention that mine comes with a clarify arm.
