Bass response may be more room dependent than amplifier dependent. I use a Creek 5350SE and drive Von Schweikert VR-1s. I don't believe there will be much difference between the 85W/ch stated for the Creek and your goal of 100W/ch. The extra Watts would only be used at very high volumes. I like my Creek. It is very neutral and clean and is worth auditioning to see if it suits your taste.
