I used a Model 750 (165W/channel) to drive Studio 60/v2's and loved the combination. More recently, I moved the Studio 60's to M200 monoblocks (200W each, comparable to the 755) to replace some ailing surround back channel amplification and have remained very pleased. My center (a Studio CC/v2) is still on the Model 750 and still doing a great job. I'd cast a vote firmly in favor of the 755.
