I agree with most above who advise not to change electronics. You have an outstanding integrated and CD player. Come to think of it, the speakers and the rest are not too shabby either!
Your amp is more than capable of driving your SF Cremonas. Do you really think another amp will do a better job when you have a great one already? Instead I would be analyzing your room acoustics and experimenting with speaker placement - especially the placement in relation to rear and side walls and listening position. Finally you said you recently purchased these products. Give the speakers time to break in. With proper placement and room tweaks, I'll bet your system will sound incredible!
