I've compared the LE3 to the NCSE and personally I prefer the LE3 for its musicality and illuminated sound. The NCSE sounds more Hifi-ish to my ears and fails to connect me emotionally to the music in the way the LE3 does. Of course this is my ears and my opinion. Others might hear differently.
LFD III vs IV
Has anyone owned both units or spent time with them to be able to tell the difference.
