Hi Oliver. I've no personal experience of the Alphason tonearm, but looking at the specs and construction, I'd certainly give it a go. It's definitely a very undiplomatic and unprofessional reply you received from OL - not good PR.
If you have the exact measurements of the cut-out needed and armboard size, send me a PM. I'm sure I can find someone to make one for you. Regards. George.
