Adwiegert, I have been experimenting with MIGs under my amp also. What really shocked me in the SR demonstrations at CES was their using them on the StillPoints rack. I was surprised that there would be further improvement on that rack, but there certainly was.
My amp was already on a StillPoints component stand, so I could not use the MIGs on this four amp stand. I put a glass shelf from my Mana stands on the component stand and added MIGs in the pin point configuration. With the MIGs was somewhat better. I decided to just use Mana stands including the same glass shelf and with the MIGs on top. Initially I thought this was about the same. But I was forgetting about the time it takes for the MIGs to settle down.
The next morning the Mana stand with MIGs was clearly better, but I had to go back to the component stand and let the MIGs settle down. By that evening it was quite clear that the StillPoints component stand with MIGs was clearly better.
One final development. I had never tried the ambient setting of the MIGs. All other MIGs were also in ambient setting. In my system at least, the ambient setting on the StillPoints stand was best. I did briefly try it on the Mana stand, but the sound stage just was as involving and real.
I have no real idea why everything in ambient works best, but for the time being I just going to listen to music.
