Shelter Harmony cart... a touch bright ?

What is the impedance setting?
I would lower it if that is easy to do.
Most phono preamps have a means to lower it.
My Benz is at 300 ohms, and my Dynavector is 30 ohms to be best to my ears.
Usually higher impedance makes the top end brighter in my experience (with an MC cart)
And lowering the impedance tames the top end.

I have a 5000. It is anything but bright compared to most of the MC's that I have. After some experimentation I arrived at 100 Ohms for the impedance. At 50 it did not have enough top end extension and was a little sluggish. At 100 it just pops with rhythm and the highs are very natural. I realize that the Harmony is a different animal, but there is a strong family resemblance between all of the new line of Shelters according to others that I have talked to. BTW, these cartridges have wonderful bass - tight, controlled, and extended.

Then, of course, one person's "bright" may not be so for another.

Thanks...I have a clearaudio balance + phono pre. It does not have selectable impedence, rather (they say) it automatically adjusts to the load it's given. At any rate, I think it (the cart) needs more break in. I have only had it 4 days. The bass is wonderful as is the with & depth of soundstage.
