skipping problem - Marantz TT-15S1

Trust me, i have adjusted the anti-skate as far as it will go. It helped, but didn't solve the problem.

I had the same table you have, the TT-15S1 and it did the same thing. I checked and rechecked till I had enough. I couldn't figure it out. So I returned it to the dealer I bought it from and got the Rega P5 and now I'm very satisfied. I never cared to find out any thing more about the Marantz. It sounds like you have my table.

Is the tonearm contacting another object at the end of the record? I know, it sounds like a dumb question, but I've made all the dumb mistakes one can make (I think), and that was one of them. The back of the tonearm was contacting the wall of the shelf at the very end of the record!
I also had a problem where the cueing mechanism wasn't level, and contacted the tonearm at the end of a record. That caused skipping.
If it's none of those, then it sounds like you have way too much anti-skate, and the arm is being pulled back to toward the arm-rest.
Does the Marantz have an azimuth adjustment?
Is the table itself level?

Hope this helps.

That is actually good to hear. Makes me think it isn't just me. I really love the sound of this table and would like to get it to work. I'm going to give Marantz a call.

TFK-
No, there is nothing that it actually contacting the arm, and i used one of those laser-level things to make sure it is level. It does seem like the arm is being pulled back to the rest position, though.

You are correct the Marantz sound good when it's right.
My problems started after just 10hrs of playing. On top of that Music Direct set it up for me and they are very very good at setting up tables. I fiddle w/ it for hours and gave up. Good luck.
