Have thiel 3.6's. Will mcintosh ma6600 work?

My Thiels sit in high ceiling open room. But have not been connected up and played for at least 8 years. Partially due to waiting to get enough cash together to do them justice. Recently considered that the mcintosh integrated mc6700 amp might work. The integration, I think would be an upgrade of my preamp adcom GFP 565? The Amps are 200wpc, so concerned that the wattage won't give me the detail and sound I have waited all these years to hear. Will these macs disappoint the requirements of this needy speaker?
