I disagree heavily. The amp is fine, especially at the distance I use. I know this because I've also tested the LS50W which is self powered and I could barely tell a difference from my passive LS50s when I had turned the DSP bass boost off on the LS50W (so they got returned).
The D3045 is 50w per channel of stable power - that means at any ohm dip it stays 50w, unlike most other amps. Plenty of power. The Aria 906's actually dip down further than the LS50s do.
As for the B&Ws, you really just need to look at their frequency graphs - they're absolutely awful if you want an accurate sound. B&W employs a house sound that is very much hate it or love it. I tried some 685's in the past and knew I hated their house sound.
The main thing that gets me about the LS50s is they have a very characteristic bump in the 2-3KHz region that is an infamous fault of the tweeter KEF uses. I've been used to it for quite some time and simply wanted to try a speaker without that bump.
See these listening windows comparison graphs:
Aria 906:
KEF LS50:
The Aria is much smoother in the treble region compared to the LS50 (fewer large bumps are better), which a very slight more warm bias (although both are still considered bright speakers).
And here is the 705 S2 (couldn't find a graph for the 706 but it will illustrate what I mean):
B&W loves doing that to their speakers and I absolutely hate it.
First and foremost as I said, I knew you would disagree, but 100% that amp is not getting the best out of those speakers, otherwise that amp is the only amp anyone ever needs!, that amp is not magic, it has it's limits, if your looking at £1000 inefficient speakers then that amp is going to be a weak link in the chain, I have not met one human being that would agree that a 50w amp is getting the best out of the LS50's, they are known to scale incredibly well with higher end amps and clean power, they suck it up and they open up amazingly, more air and the bass comes through better.
I do agree that B&W have that 'House sound' I have a few of their speakers, but that has changed quite a lot with their new generation of speakers that use the continuum drivers, interestingly that video I posted the reviewer also wasn't a fan of the B&W 685's either.
edit -
This what the LS50's can do with a proper amp,
Obviously I'm not saying go out and grab a 4 grand amp but it just shows how well the LS50's scale.
