Since the introduction of the 1ET400 many have wondered when Purifi will deliver a more powerful amplifier so that large speakers like the Revel Salon 2 can be fully driven. More power without sacrificing the remarkable performance of the 1ET400. Some serious competition to McIntosh, Bryston, Krell etc.
Compared to the 1ET400, the 1ET7040 appears to offer a little more voltage swing but principally more current drive (40A peak vs 25A peak - so about the same as a Hypex NC1200). For most speakers the voltage drive will be the limitation so the 1ET7040 is not a significant advantage unless 2 amplifiers are used in bridge mode per channel (then perhaps the current limit should have been set at 50A?).
So what’s the hold up? Here are a few thoughts. Firstly Purifi have been working on their loudspeakers - just beginning to bear fruit. Secondly the very high power market is quite small. Thirdly the 1ET400 is a pretty hard act to follow and the preliminary performance of the 1ET7040 perhaps isn’t quite there . . .
