Audible Illusions 3A MM or MC phono board?


I recently purchased an Audible Illusions 3A from 2003 with MM phono board which I use with the Reson Reca MM phono cartridge (improved Goldring 1042).
I also have a Reson Etile MC cartridge (improved Goldring Elite). I am unsure now whether it is worth the money to upgrade to the AI MC gold board so I can use the MC cartridge. I live in Europe so I guess installing a new Gold Board will cost me about 1000 USD at least. I have tried to contact Audible illusions to find European distributors, but no response. Is there anyone in this forum who can advice? Is it worth the money and hassle to upgrade the AI phono board? And if yes, where do I get one? Thanks

Now it takes years? Wow. I'm not sure exactly what percentage of that preamp was designed by Bruce Moore and John Curl.

Correct me if I'm wrong but I believe the Gold moving coil phono section was designed by John Curl. Parasound is currently marketing phono preamplifiers designed by John Curl and are said to be extremely well designed and a good value.
A year ago Art installed the gold phono board so I could use my Dynavector XX2. Turnaround time was two weeks and I'm immensely happy with the upgrade.
