Belles 150A Ref vs Plinius P8 or 10

Has anyone been able to compare these amps or have opinions on one over the other? Thanks, Tom
Belles amps have been among the darkest I ever tried, although others have had much better results so it really depends on the overall system. I've had both the 150A Hotrod and the 350A, based on others rec's. Sorry, no experience with Plinius here.
