    The turntable that took the spill was an AR fitted with a Decca unipivot arm. It was basically okay, just dinged up.

    Now many years later, no progress to report. Still using an old AR-XA, but with stock arm. It sits directly on my equipment shelf, and the stylus gets the shakes when I walk across the room.

    My dream is to own one of the better Teres tables with the high mass wooden platter. Chris Brady lent us his best unit when my partner and I demoed our speakers at the Rocky Mountain Audio Fest last year. It was an incredible signal source, the best I have used by far. Chris's products can be checked out at

    No pics yet (digital camera is on my to-do list)
    Its an old Pioneer turntable with a Audio Technica cartridge. I think I run 1.25g on tracking and anti-skate. When I crank up the volume that bugger starts hoppin pretty good.

    The belt drive helps to isolate vibration from the drive motor. Just like the cheap solution to put the turntable on a slab of foam rubber. Rock on Morbo...I like your honesty.

    Wouldn`t a better way be the direct drive system that technics used.
    That just floats and is run by magnets ,So in reality the platter is part of the motor.
    Or are their some patent issues?
    just thinking because people pay alot of money for these fancy turntables

    That's the beauty of the latest generation of digital audio. Dont need a $10K turnatable and tonearm/ cartridge combo for pristine sound.....more audio voodoo.

    The table we used at RMAF was his first edition of the model 360, then considered a prototype.

    The general reasoning behind the current generation of high mass platter belt drive designs is to achieve rock solid speed stability and isolation from motor vibration and speed variations. The inertia of the heavy platter resists any change in speed, and tiny instantaneous changes in motor speed are additionally filtered by the drive belt. A system like this looks like gross overkill at first glance, but there are large gains in sound to be had from this approach. Although we were afraid of lunching the $5k Koetsu cartridge when we used this 'table, we were constantly thrilled by its performance.

    Your post on the counter weight got me thinking.
    You balance the tone arm then 0 in the dial.
    then adjust to 2.5 grams
    This should be the correct setup for most turn tables of our era
