I bought also one some time ago and:
1. you need also the special riser from aranet
2. it worked for me with Vampire V2, but you have multiple connections: (1) from cd32 to riser, (2) from riser to 1200-adapter, (3) from 1200-adapter to Vampire V2. I had to align perfectly all 3 connections, then it worked stable, but as soon i moved my cd32 and the ideal constelation of the 3 connections was not anymore, I could spend 45+min to get it back working. After the 3rd session, I just gave up.
