Not knowing your cables, I will assume the cables are not the problem.
I would try to demo a different digital front end and see if that is your problem. Try to demo a nice one box CDP. If your sound is still grainy, the next likely suspect is your preamp. Make sure all of your tubes are good. Maybe even try a backup set of tubes if you have one. See if you can demo a nice preamp. If grain is still persisting with a demo preamp.... Make sure all of your speaker drivers are functioning. You could possibly have a blown or have a defective driver. You might want to check your speaker drivers first.
If none of the above solves your problem, well it is probably your cables. You need to demo different cables to see if that grain goes away.
If it's not your ICs or none of the above... you might want to goto an ear doctor and have your hearing checked.
Good Luck!
