AURIS HA2 SE 1599 USD My Full Review http://earphiles.org/2017/05/auris-ha2-se-review/Pros Excellent balance Good dynamics Very versatile and sounds good with a wide range of headphones Lovely build Taut and punchy bass Cons The amplifier can have slight hum depending on the headphone used. Mainly high impedance ones but when music is playing it goes away. The Kennerton Odin has no hum and the Meze classics have hardly any where as the HD650 and Atticus do. Edit: the amplifier is very sensitive to power quality. Hum is a non issue now. Slight haziness in the treble The Auris is one punchy and controlled piece of gear that scores very high in most aspects. I recommend it. If anyone else gets one I would like to hear their thoughts of it.
