I can't speak to the Electrons because I have not heard them, but I have heard the DI speakers and ended up ordering a set of mini Ulfs from that.
Speakers I heard were Sonus Faber, Wilson, Paradigm (both regular and Persona line), B&W, Martin Logan, Legacy Audio, and I'm sure some I am forgetting.
