Sabre is a good balanced between power consumption and SQ, hence a lot of portable player manufacturers choose them. Anyway, I prefer BB and AKM over Ess though

I've bee told shozy has a number of great upcoming daps. I wish the above dap had a small OLED screen

I have a Dragonfly Red. Even though it should be a little more effcient than the Black, Ampere also reports a difference of around 50mAh. This is measured between playing music from the headphone out and from the Dragonfly Red. However the Ampere app does not to seem very exact

Fantastic, mounting it onto over the ear headphones is exactly what I'm looking for!
