I almost went for your same speakers back in 1987, but opted instead for Vandy 2C's; either would have been my first high end speaker. My impression of the SP1's lingered for awhile, making me ponder what could have been.
Those Graham LS 5-9 speakers really caught my ear at Axpona a couple years ago. Wonderfully natural sounding.
Here's another thought: you clearly like the Spendors. Maybe consider rebuilding their crossovers with higher quality elements? They very likely use some electrolytic capacitors that are getting tired and could use replacing anyway. Done right, you would keep the frequency balance character of the speaker and likely get a more informative presentation of that voice that you like.
