You may want to double check that. I'm pretty sure the Sadie's amp is also 250mw. The Mofi had the 240mw amp built by Fiio. All the new headphones have amps built from the ground up by Blue. I don't know the impedance for the Sadie when amped because I don't own them, but the Ella's go from 50 in passive to 10 when amped. But these planar drivers are power hungry bastards. I'd be willing to bet that both the Mofi and Sadie will be able to play much louder in amped mode. Like I said, I still average at around 80% volume with amped mode on, on most songs.
shure,
No it's not.......see here.
Yes that is all true that the MoFi was the first and LAST Blue headphone to feature a FiiO-built amp.
The listed impedance for the Blue MoFi, Lola and Sadie is 42 ohms, while yes, the Ella's is "50 ohms Passive; 10 ohms Active" as you stated. I see.............yeah, given what you said about planar magnetic drivers, then yes, it's quite possible the MoFi & Sadie will play louder.
