cheapest hmm depends on where you live I suppose. I sold my pimeta amp built by misterX but I would believe that would be quite fine for the 900. As a bang for buck solution. Sky is the limit lol.

I currently run the Slee Solo and are awaiting the goldpoint headphone pro. Canamp has amazing soundstaging but it´s just to warm for the 900 I feel.

Ultrasones pair nicely with the RudiStor amps. You may be able to find a reasonably priced second hand one.
