Me neither, Martin. Good post, btw - I concur with most of your observations

However, returning to what I wrote earlier:

Therefore some documented measurements, showing the speed stabilty of the drive system using the stock platter (powered by the standard Timestep PSU) before, and then after the new platter and HE PSU mods have been installed, would be useful - and that's where Dave comes in.
I presume that such a thing can be measured and documented for our perusal?

I'll require this information (or similar evidence which satisfies my concerns above) before I'd consider buying the new platter, as this is one modification the effects of which I'm unwilling to judge solely by subjective analysis.

There's a time and place to be anal about measurements, and this is one of them!

Marco.
