Dynavector XV-1S impressions?

My XX2-MK2 was forward and bright till it broke in, which took 30 hours or so.

I find it lovely, and not how you describe it. You don't give any other pertinent info, but it does take a while to break in if yours is still new, and your setup may be affecting the sound. And, each time you play it, there is a small window of warmup time.

I too disagree with your impressions. I assume your cartridge is either not broken in yet, or you have not adjusted the gain and/or loading to get the most out of this cartridge.

Can you tell us what your phono stage is, along with the gain and loading settings that you are using?

The XV-1S is the absolute best cartridge I have ever heard, both in my system, (past cartridges include Koetsu Rosewood Signature, Shelter 90X), and in my friend's system, (his past and present cartridges include Koetsu Rosewood Signature Platinum, ZYX Universe, and an EMT, although admittedly, the last two are probably the XV-1S's equal, just with different strengths).

My two cents worth.

I've found the XV-1s and XV-1t to be frightfully "nervous" out of the box.

After 10 hours they begin to calm down.

Be patient.

Also check your alignment and loading.

Just for the heck of it, what is your "set up"?
