Holy cow! I assume there is some benefit there as the amount of force it takes to move from track to track is reduced???

The table looks like a piano and the tonearm looks like a violin bow complete with a bow in the wood. Pretty funky looking set up, including the belts that looks like they aren't lined up correctly.

You've kind of got it :) The arm is "tunable" like a violin bow :)

I wonder what the effective mass is for that baby!

Does it still need antiskate?

Good question. Will see if I can find out. The length is chosen to minimize tracing error but somehow suspect it does use antiskate, that is if you use antiskating.

Midwest fly over state..
Seems like you'd affect tracking weight when you apply the rosin.

Somehow I doubt that this is a good sounding tonearm. Are there any reviews available?

Another long one, from psycho Romy's site.

Even if there were....most aesthetically unpleasant to view. Just plain ugly.

I feel there would be a problem with warped records, the inertia of the cartridge in the vertical axis would make the suspension bottom out at times. Probably only pristine records could be played, or you would need some sort of very effective clamping to flatten the surface, such as a vaccuum system.

These silly long arms are made by people who don't really understand the physics of what is going on, in a bid to reduce the angular distortion found on pivot arms. Much better to go tangental if that is really bothering you. Having a long arm like this puts a load more mass to move, plus I hate to think what resonant modes are pinging back and forth on an arm like this. Colouration must be awful. Tonearms should be zero mass, infinite stiffness and zero friction. So its a tossing game to get as low a mass, with the best stiffness and the lowest friction possible in the real world. Making arms this length makes the arm very low stiffness, high mass and depending on the bearings, because of the weight, higher friction, with loads more bending modes. A nightmare! Even worse are ones made with a violin bow for Pete's sake.. unless of course one likes the sound of vinyl like that.
