What is the best arm for a Linn Soundeck 12

You'll do just fine with the Ittok LV II. There is more of a difference between the Basic and Ittok than the Ittok and Ekos.
I use a Dynavector 10/5 MC with the Ittok. You can use your same armboard if staying with Linn. Also, so far, the the lengths are the same for each arm, so a custom Mint LP will be an excellent tool for mounting a cart. If you switch up to the Ekos, you can still use the mint LP.

Best LP12 I've heard so far was Aro/Keel with power supply upgrade.

My local dealer has been selling LP12's since the beginning. Every one of the guys who works there (except one) has a Graham arm on his LP12, either the 2.0 or 2.2. The one guy who doesn't has an Ittok because he can't afford the Graham. I find this quite interesting.

Hi Juan314,

I had a Linn LP12 for about 20 years. The best arm I had on it was a Graham 2.2. I have heard Ittok's and Eko's (which I liked a lot), but the Graham will play with them. I have not heard the Naim Aro which is supposed to be very good on a Linn.

Good Luck,

Mark

Not very common these days, but my Well Tempered arm works very well on my Linn.
The WTA arm is light enough not to bother the suspension of the table and
the benefits of no bearing on the arm are substantial IMHO.
