Equipment Set-up Recommendations?

Tracking at 2 grams should be plenty heavy for most any cartridge. Given that your pivoted arm seems to not have this problem, i would assume that it has something to do with the way that the air-bearing arm is installed. Then again, the pivoted arm may be experiencing enough side-wall thrust & drag that the friction "holds" the cartridge in place. Otherwise, if the arm / table truly are level in all three planes ( front to back, side to side and diagonally ) and the arm is installed properly, the table simply lacks proper isolation characteristics and / or the rack itself doesn't isn't nearly as good at isolating floor-borne vibrations as advertised.

Given that some of the most fondly loved and reviewed turntables suffer from such a problem, that part of the equation would not surprise me one bit. The fact that the Adona's support the shelves directly under the component also leads me to believe that it would transfer more energy than a rack that supported the shelves from near the edges.

The idea about mass loading the floor in the area near the rack may help somewhat, but you can expect it to change the sonics of the system for the worse too. That is, i think that you'll find that the sound will "dry up" quite noticeably and the bass will become far heavier and less distinct.

Personally, i would suggest going over the arm installation again. Please keep us apprised of what you end up doing to correct the problem as there are many others that are interested in this arm. Sean

Gregadd: You solved the problem by avoiding the problem. That is, you purchased a real turntable with real engineering behind it. This is not to say that it is a perfect machine, but that it had taken far more steps in the right direction than many of the alternative designs on the market. Both back then and now.

As to weighting down the floor, the results would vary with how much weight was added. I guess that there would be some type of reasonable trade-off between reducing floor-borne vibrations and muddying up the presentation. I ran into this when changing racks and the only weight added was the rack itself. Given that i went from a rack that weighed less than 40 lbs to a rack that weighed in at appr 170 lbs, there was no way for me to experiment or fine tune exactly how much "mass loading" i should use. The end result was that once i got rid of the massive weight of the rack, the sound of the system came back to normal. Sean

Raul: "Anyway, the MG-1 is not an Air Tangent"

What in the world are you talking about here??? Sean

Raul: Sorry about that. I misunderstood what you were saying. I thought that you were saying that this is NOT a tangential tracking air bearing arm, not that it wasn't a Air Tangent ( specific make / model of arm ). My bad... Sean
