https://forum.audiogon.com/discussions/furman-smp-is-not-real-series-mode-surge-technologyFurman does not license series mode surge technology. They were sued by Zero Surge - the originators and license owner of the series mode technology patent - and lost. Furman was forced to call their technology SMP (Series Multi-Stage Protection), which still uses MOVs.
Real series mode surge protection does not use MOVs, because MOVs degrade with surges. This is the whole reason series mode surge technology was invented, to avoid the use of MOVs.
