I believe the amps would need to have the same gain in order to keep the volume tracking correctly from both drivers. I do not know if the Alpha 8 and Alpha 10P have the same gain. However, I have e-mailed the US distributor Audiophile Systems Limited a few times in the past with questions and they were very helpful. I would suggest you contact them. Here is a link to their Support Page:

Hopefully they will be able to answer your question.
