Actusreus,
The "magnum" moniker indeed designates as an upgraded model. The Rogue website currently lists the Ninety-Nine Preamp as "99 Magnum."
I believe too that enhancements that bring the "magnum" moniker eventually become standard on later prodcts, so the moniker is not always carried forward even though the enhancements are still used. That might be a little of what's going on for the 99 at this point. It's called the "Ninety-Nine Preamp" in the headline, but the "99 Magnum" in the line where the price is given. But all current 99 preamps are "magnum" versions.
