This is an epic headphone amp able to produce 20W into a 30 ohm load, but it has a brilliant volume control that can keep all that power in hand for more sensitive headphones.

Sound is generally smooth, but detailed, agile/articulate and with excellent presence and authority.
There's a great review here by @project86 https://www.head-fi.org/showcase/cen-grand-9i-906-silver-fox.26606/

4 output modes help to tweak the sound character and also reduce or increase gain as needed.

Lots of inputs and outputs

Fully balanced design and uses the same Exicon Lateral MOSFETs as are used in the awesome Enleum AMP-23R.

Happy to ship anywhere, but please note that it's a 230/240V only design and is a large, heavy amp so will cost a fair bit for international shipping.
