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 :)

There's a lot to be said for a good powered monitor, glad you like them....  over the years I've owned three pairs of KEF,   their latest offerings continue to deliver great sound.  
When you use Bluetooth from your computer, is it digital to the DAC in the speaker? USB is digital, is Bluetooth?

Even the passive LS50s are leaps ahead of all B&W speakers I've heard. They  easily compete in the $4K standmount realm. Some say they're merely good, but I suspect they heard them with low quality amps. It's the trailing edges of notes, the "decay" that really sets their midrange apart from competitors. The highs are detailed, yet non-fatiguing, and their imaging is hard to beat at any price.

Aren't these LS50 wireless speakers EQ'd, the back panel shows several EQ options.  That and 230 watts per speaker (200 for the woofer, 30 for the tweeter) are going to give a certain advantage over a traditional pre amp and amplifier.  But it's an apples to oranges comparison.  The EQ function is giving anything but a flat frequency response.  Some will like certain frequencies pushed to the foreground.
