Which cart works with Ortofon AS309S 12inch arm

The 309S can hold up to 25grams (cart + headshell weight) otherwise, you need a heavier counter weight which is also available from them. Need to check the headshell weight. Ortofon has 13.5-16.8 grams to match with your carts.

Based on my limited research, there are 4 diff headshell options: 12g, 13.5g, 8.5g and 16.8g.
The std counterweight is 18-25 grams.
correct me if i'm wrong.
if a cart is say 7.1g & I use a 13.5g orto headshell,that gives me a total weight of 20.6 grams.
So, that should in theory work correct.
Just in same way if a cart is 11g and I again use their 13.5g headshell. That totals 24.5g, so i'm still within that 18-25g range.
Are these assumptions correct ?
I guess its best to have multiple headshells of different weight so one can have more flexibility ?

I have the AS309S on my Raven AC-3. Almost all cartridges I have tried on it sound good.

As Raul said, with removeable headshells, the world is your Oyster with combo's.

Empire 1080LT MM cart sounded really nice.

I currently have the Ortofon SPU Royal GM and its sound glorious.

enjoy

Interchangeable Headshells will give you more options. Different folks & have different strokes as they say. May it be pop, rock, jazz, classical or vocals you will have a cart that will do justice to your records. May it be audiophile nor regular/old pressing.

goodluck

Thank you for the replies!
