integrated amp suggestions solid state

i have been using a sim i5.3 for over 2 years now and a friend suggested to get something with more power(current).I listen to mainly jazz and classical.I have been looking at musical fidelity higher wattage amps and wonder if thats movin down the rung.I am working with budget so going to the evloution series would hurt,My speakers are addagios, cdp i5.3, az cabling.Some suggestions would be appreciated.Looking to stay solid state...thanks
