Q106, to obtain a Marian Trace Alpha, it depends where in the world you are, there is a list of dealers for this card on Marian’s website,
http://www.marian.de/en/shop/international
otherwise, try your local google and see if it can find local sellers for you or find a local pro-audio stockist who is a Marian dealer as they may be able to order one for you. If all else fails, contact Marian direct via the website above as I am sure if you cannot find a dealer locally, they will sell and ship you one.
The Juli@ card (I also have good results using the Maya44PCI) would be a good second choice if you cannot get a Marian but the Juli@ will require tilt calibration whereas the Trace Alpha does not.
Hope this helps,
Yorkie.
