@audioman58 , by what definition do you define reference level? Popularity? Lots of write ups? Many many people do not like B&W speakers, not even the 801. As a speaker guy, there are some excellent things about this speaker, however, I always feel like they got it to market before they finished it as they always seem uneven in the upper treble. Maybe in a few years I will no longer care as I can't hear it.
What do you think Bricasti amplifiers do that cannot be done in a power speaker. This is where @donavabdear 's comments come in. A class- D amplifier can easily keep up with the Bricasti for the bass frequencies, and then a good quality A/B amplifier would have no problem matching for the mids and high frequencies, both perfectly matched to the drivers they are connected to.
The 801 has almost too wide a dispersion for many home installations. It has a lot of energy off axis which can result in it being viewed as bright without adequate absorption. This is a common complaint. The Genelec is tuned to be near ideal for many installations. Most Genelec would require a sub to compete for bass frequencies and level. I expect the distortion of the best Geneiec equals or is lower than the B&W Bricasti combination. Less distortion, less lost details.
