Recommendations for Adjusting F5 Turbo Monoblocks to New Speakers

Hi all,
I recently acquired a used pair of Revel Ultima Salon 2s that I'm hoping to use with my F5 turbo monoblocks (assuming they have enough power). My current configuration is 42V rails with the source resistors biased at .2V. This results in a heatsink temp of around 50C.

I'd be willing to switch out the transformers in the monoblocks to a lower voltage and increase the bias if that would be more optimal for these speakers. I would appreciate any thoughts and recommendations.

Thanks.
 
I have speakers of similar sensitivity and impedance (KEF R700) I use with my f5T. It really depends on your volume needs and how big your room is. More bias sounds very obviously better but it's a trade off between power and bias. If you don't listen loud (say 85db average) and don't have a huge room I'd think 32V rails (50W output) might be the best compromise.
