New Kleos SL on the Table
I just got this up and running about 1 week ago and it sounds better every side. I have it mounted on a VPI/JMW Aries 1. Just one problem though, when i put the stylus down on the lead in groove it zooms right into the record, sometime skipping into track 1. VTF is 1.75g exactly, neutral vta(headshell bubble level), no dampening fluid yet, wire curve is natural. Any Ideas? If I hold the stylus in the lead in for a sec it sort of catches and works fine. Never had this issue with my ruby. It really sounds amazing though!

Is the table level and is there perhaps too much antiskate?

The table is spot on level. I have no antiskate on the JMW memorial tone arm. They state you can twist the wire from the tonearm to the junction box against the twist of the wire. It is now in the neutral position, ie no antiskate. I thought antiskate exert an inward force? So I in effect have way too much antiskate now?

ANTI-SKATING:
A pivoted arm without an offset head would not be subject to skating force. However, it will also have no correction for tracking error and the resulting distortion is unacceptable. As soon as the arm's head is offset to lower tracing distortion, skating force arises. Greater offsets result in greater skating force. The 12” arm has a very small offset angle and therefore a very low skating force to deal with.6 After very careful listening tests we have determined that every tonearm we tried sounded better with their mechanical anti-skating disabled and the tracking force very slightly increased. All mechanical anti-skate devices add a negative sound to the music because they are made of parts that can vibrate. We solve the problem in a unique way: As mentioned earlier, the arm wire applies the anti-skating force. The degree of force applied can be adjusted as explained below. To increase or decrease the amount of anti-skating force applied, simply unplug the Lemo connector and twist it in the direction you want the force applied. For example, to increase anti-skating force give the connector a counterclockwise twist, unwinding the coiled wire. Likewise, to decrease the force, give the connector a clockwise twist. Remember, the Lemo connector can only be "adjusted" in increments of whole turns. If it is not, its key will not line up with the groove in the receptacle. We could go on discussing the pros and cons of how much anti-skate is correct, but the sonic answer is very simple. Adjust the wire as mentioned above until the tonearm drifts outward when set to neutral balance. When you push the neutral balance floating tonearm towards the center of the record, it should push back out towards the rim of the record. Very little force is needed to do this, and the wire acts like a spring to supply this force. If you try adjusting the anti-skate with a groove less record or a test record you will ruin the twist in the wire and void your warrantee Double check the horizontal balance, lateral balance, and tracking force and adjust as needed. Increase the tracking force by 1/10 of a gram above the cartridge manufacturers highest recommended force.

Thanks Myles. I tried putting a twist in the coil direction a couple days ago and it didn't seem to change it much, maybe I'll add two twists. I'm hesitant to add addition VTF because of the way the coils align in the Kleos, they seem pretty set on 1.75g, any thoughts

I just took out an old record and did 2 twists from neutral with no change, still races inward....

I know next to nothing about this area, but from what I read above, it sounds to me like you should be untwisting, not making it tighter by adding twists.

Randy Untwist adds antiskate, antiskate pulls the tonearm toward center correct? I already have too much force towards the center.

Skating force with an offset pivoted arm pulls the arm inward towards the record label. Anti-skating attempts to compensate for this by applying an equivalent outward force. So if you want to prevent your arm from skating inward on the lead in groove you need to increase the anti-skating force.
