A question about these.

I see that the 902 is well liked and recommended for home use. I have a pair of 802-8D. Is this a similar motor? Of course they have the Symbiotic frams, which I don't like. But could they become a 902 with better frams?

I also have a pair of 806 and find them much smoother and better balanced than the 802. I would love to get the 806 sound out of the 802 but with better high end.

Bottom line. Can the 803-8D be upgraded to something similar to the new 902?

Thanks!
