thats seems a lot. The upgrade from schist is 350aud theres a fairly big premium there
From Schiit you would have to add freight there and back which would be around 200 AUD, so 580 AUD not such a big premium.
Edit: I bought my Bimby direct from Schiit, it cost 949 AUD inc. freight, Addicted to Audio price 979 AUD, if they had had them in stock when I ordered I would have bought from them instead.
