I have an SP16 in my system and I can assure you that imaging is not an issue. I have not heard the SP8 so I can't say whether it would be an upgrade.
I can say that one the biggest upgrades I made was the purchase of my Benz glider. Again I can't say whether there would be biggest difference between it and your sumiko.
One final point, a big determinant of imaging is your room and equipment placement. If I were you I would start there. I hope this helps...
