Is break in quicker with Planars and Stats?

I've had 2 pair of Maggies.
Original MG-1s rebuilt at the 20 year old mark were
very different upon return and needed months at my modest listening schedule to return to 'normal'.
There replacement, some 1.6s were weird! I was sitting listening after original install and the stereo image wavered from left to right and back again, several times fairly quickly. I was absolutely SOBER, too, so don't even say it!
They settled in fairly quickly and never repeated the image thing.
I, too, would have been a little leary of speaker break in but am now a believer. I think speakers break in quickly for the first say.....8 or 10 hours.

Sounds plausible!

Norton, Before buying my 1.6 Maggies, I'd have had a similar opinion to yours. After listening to my new panels have the stereo image go right/left left/right fairly rapidly, within an hour of firing them up, I was changed. The 'forming' of capacitors and slight settling of the mylar is a reasonable suggestion. It has NOT happened again. The amp used, a Rotel RB-1070 had several hundred hours on it so was reasonably well conditioned.
I hadn't had a DROP to drink, and imbibed no mind altering substances. This was a stone-cold, out of the blue effect and very unexpected.
