Sticking with the Stax system I decided to sell the very rare DNA Stratus 2A3 too.
If you want it you have to order from Donald in USA and wait an year:

It's amazing with every cans, Susvara included, as many knows is awesome with the HD800 and all dynamics.
Very difficult for me put this for sale, but I travel a lot and move home often and is heavy to carry with me, hence is for sale for someone that knows the amplifier.
It is like new, no signs at all. The amp comes with a pair of Shuguang 2A3C-T Nature Sound; an Emission Labs 5U4G; and a Russian 6N1P tube.
asking 8,000AED, but UAE audiophiles will have a better deal when come to listen.
