Yep, 2.5 to 2.7.  I know that is not what their literature says, but it makes a difference.  Try it and see what you think.  But I have heard this from multiple sources and I run mine heavier.  It definitely sounds better.   Rock on

Hi, I have both.   If you are running a dynavector, make sure your tracking force is heavy enough. You actually need to run these heavier than typical, usually around 2.5.   Hope this helps!  Vinyl is awesome through the Wells.
