KEF LS50 Wireless -- wow!!!

Today I bought a new pair of the KEF LS50 Wireless speakers for my study (10 x 13 x 12). Just so you know my main system in the media room (15 x 20) consists of a pair of Bowers and Wilkins CM10s2 ($4000), Parasound A21 ($2500), Cambridge Audio  851D ($1000), Double Shotgun silver wires ($350), power cable from Cerious Technologies (Graphene something -- $350), with a total cost of something around $8k. 
I thought it would be fun to put the KEFs in the same room as my main system and play them side by side using Tidal streaming for both. Now keep in mind that the CM10s have several hundred hours on them, whereas the KEFs have probably less than 2 hours so far. The speaker stands for the KEFs are still on backorder, so right now they're just sitting directly on the media console (glass top) -- in other words, this is a totally unfair comparison. Also, the CM10s are placed about 9 feet apart and 4 feet from the wall, whereas the KEFs are about 6 feet apart and less than two feet from the back wall. 
What I heard was totally unbelievable!!! The KEFs, which mind you, are not broken in at all, not sitting on a proper stand, and not as wide apart from each other as the CM10s, totally blew the CM10s out of the water. The sound coming out of the KEFs is more full-bodied and balanced, beautiful midrange, and a very satisfying base. The imaging is just so much better than the B&Ws. I just can't believe how a speaker which is literally 4 to 5 times smaller than the CM10s can produce such a rich, satisfying base. I think the only aspect where the CM10s have a slight edge is the soundstage. But, I suspect that might improve with proper stands and more play time.
A few weeks ago, I auditioned a pair of Harbeth M30.1 in the same media room (driven by Parasound A21). While I really liked the midrange on them, they sounded a little thin to me. The KEFs, on the other hand, have a pretty good midrange (probably not as good as the Harbeths), but to my ears, they sound better in every other aspect.

Now, I'm not saying that these $2199 speakers are the ultimate bookshelves. But they sure beat my comparatively more expensive setup by a mile.

All hats off to the KEF engineers! 

P.S. The CM10s will be on the market pretty soon :)

Has anyone ever used a Killawatt or something similar to see how many watts the LS50 wireless draw? 
I have a specific use in mind and need to know how many watts the pair will draw at average listening volumes.  Can someone please help me with this?
thanks!
ps, the specific use is on a cruising catamaran and the speakers would be powered off of an inverter, and since this draws power from the house batteries, power consumption is a concern.

Doesn't your boat have an ammeter? You could turn on the inverter and see what it reads. Remember, the specs from the company would just tell you what the draw is at 120 volts. You need to account for the losses from the inverter.

I also recently bought a new pair of these in white with matching stands.  I have the stands filled with sand.

Ultimately I purchased these for bedroom speakers but had them in my main listening room for some break in time.  Even out of the box I was hugely impressed with the authority and resolution that these speakers play. 

The bass response blew me away for the size of the speakers. The bass is not just a one note wonder either.  It's layered and textured with a nice hit.  Imaging is top notch and these are very musical.  An absolute steal for the technology, adjustability and sound you get at this price.  It will be a shame to have them in the bedroom as I could see these being someone's main rig if they were on a budget.

I also tried them out with my JL E110 sub and it integrated very nicely but not a necessity depending on your room size. 

I almost didn't want them to sound as good as they do for the price.  It really makes a person start thinking of all the money and time he/she has invested in the past to get the sound we're at now with our main rigs.  But that's also half the fun!

Hfaddict, 
Did you try these with any rock or metal?

@mofojo No, most of my listening was folk, blues, electronic etc.

I will say the biggest downfall of these speakers to me was at low volume listening. They do require some volume to come alive.  But I am also used to my Audionotes that start hopping at quite low levels.
