Just an update to my experience with the LS50w so far:
Clearly, the biggest difference with these compared to the LS50s is the DSP that results in higher bass output. That completely changes the way your brain perceives the sound output of this speaker and explains why so many say it sounds better. We are bias to louder, lower frequencies as a natural thing.
I am not entirely convinced at this point that you couldn't get something similar or better with a regular LS50 + a sub. There's no replacement for displacement after all, and forcing that tiny driver to pump out bass down to 40Hz will increase the Doppler effect on the higher frequencies - no way to avoid that.
You could point out the amp power and matching, etc. The problem is... whatever difference it makes seems extremely subtle to me if I can even detect it. Then again, I'd start riots in here with my opinion that properly built amps (especially digital ones) make sod all difference to the sound of a speaker (unless you need more power to fill a room, of course). I've yet to come across an amp that I have said 'yep, this changes the sound' and not concluded with 'my brain is just expecting a difference and thus I mildly perceive one'. The literature seems to back me up on that one but that's a debate for another time and place. The real secret sauce is room correction with stuff like Dirac Live, imo.
I don't think Ken is wrong by saying that his LS50 + sub + dirac live setup will trounce the LS50w. I entirely believe it, especially with the dirac.
The app is a bit wishy washy. It works, but it doesn't feel like a £2k product should. I don't mind the remote design but volume control on it is finnicky, with no way to see what the volume is except by ear. Problem is, there's a lot of volume steps and you can't configure the steps a button press moves the volume by. That can only be done on a phone.
For an all in one system it still has its benefits, but you'll lose the ability to update said protocols such as Bluetooth just by updating an amp or something, which is always something to take into account.
So for now, I am not sure I'll keep these. Only a week in though so still plenty of time for my mind to be changed. I will say they look fantastic - the blue drivers are classy as hell.
