Lula,
Lacking any auditioning of the Electrons I offer no comparison. From the specifications the Impacts have a higher sensitivity rating, so if you are driving them with an SET amp they would offer an advantage.
Having spent many hours of ultimate enjoyment I consider the Impacts to be the bargain of the century in high end loudspeakers. Only experiencing them would allow you to ascertain a final purchase.
