Elise deliver different sound as Elise if fully tube amp, except the rectifier of course. Bass is more rounder in Elise.
On the other hand, bass in Ember is equally extended, but with flatter, faster response as expected from SS output stage influence. Pick your poison!
Interesting comment about the Elise and Ember sound signature. How does the Elise do with the LCD-2? or any planar that you might have tried it with?
