Major Problems with Aleph Ono

I have an Aleph Ono on loan I am considering purchasing. The rest of my set up consists of a Clearaudio Virt. Wood MM, VPI MkIII/PT 6, ARC LS15, ARC VT 200, Vandy 3A Sig's.

The Ono sounds great, much better than the Creek unit I currently use, the problem is, when I turn the volume up to even moderate levels, the woofers in the speakers ossilate and the tonearm starts hopping off the record! I have the jumpers in for the lowest output (60 db) and am using the recommended settings for the cartridge.

I have tried different loading, resistance, cables, balanced and single-ended outputs, I even borrowed a friends pre-amp and took the LS 15 out. Nothing has changed.

Obviously this is not good. I have talked to Pass (not the Ono), the guy selling it (as baffled as I), and someone I consider an experience Vinylphile who told me to move on and buy a different stage (maybe a PH3).

My question is this. Has anyone had the problem and does anyone know how to fix it?

I'd suggest placing the tt on a solid support, like a granite base. I have my placed on a custom cut base and there's no feedback vibration problems.

If the woofer wobble disappears after the first track, this may mean that the cart is not optimally set. Try checking the alinement.
