@ matrixrabbit I owned the X300A and it was, but rather good for a desktop computer speaker. I got tired of it and gave it away to my nephew.
I also have had the LS50 on my desk. I used isoACCOUSTICS stands (not expensive) and the sound was rather good though the soundstage was compressed on my desk. However, the LS50 is better than the X300A. My desk is around 5 feet long. A bigger desk would have been much better.
I am currently listening to the passive LS50 on my speaker stands away from the desk and the sound is of course much better and I am hearing the best that the LS50's can do. I will pass the LS50 to my son's room soon. Never selling this speaker.
The powered LS50 has built in DSP so it will sound better on a desk than my passive LS50. The new KEF LSX is the replacement for the X300A and it is supposed to be a big improvement. Both the powered LS50 and LSX have desktop specific DSP settings.
I just sold a Audience 1+1 V3 speaker which I was using on my desk. It was a dipole design so you need to give it space on the rear. It has an incredibly clear sound (better than the LS50), but I found the imaging better on the LS50 and off-axis listening better on the LS50 so I sold the Audience. It also fits in the palm of your hand and weighs 8lbs. Something to look into for a small space if off-axis is not a big deal for you. The imaging issue was likely due to my off-axis placement. Use isoACCOUSTIC stands if you are using the 1+1 on a desktop.
@matrixrabbit I do not know anything about the R3/300. I am not sure about your electronics since I have not heard them. There was a Christmas sale on the passive LS50 from the online KEF Store for $999 . The passive LS50’s can be found on A’gon used for less than that.
I’ve heard all of the ones mentioned except the X300A. I have passive LS50’s on my desktop now, but would have the LSX if they were available when I sprung $900 for the LS50’s that really are a little too large for this application. The LSX is a killer speaker for the size and the money! There are myriad other ways than USB to get music from a computer (digital optical or Ethernet) and of course wireless & Bluetooth.
The R300 at the current price are a great value, but for near-field use I feel there’s too much separation of the Uni-Q driver and bass driver. Same goes for the R3, and profoundly YES they are worth the money...as stand mounted speakers in a larger space.
The X300a could not compere in sound quality to my passive LS50's on my desktop (both on isoacoustic stands). I agree with a poster that the LS50's are a little large for a desk. My desk is 57" long but it was still better to me than the smaller desk oriented X300a. So what that should mean is that the wireless will be even better than my passive LS50 because the wireless has DSP created for desktop usage. I think the X300a did too, but that would have been older tech and I liked the passive LS50 way better.
Matrix we are a long time Kef dealer with all the models you are considering on display.
You have a few options if money is the driving considering run to get the R300 for $1,200.00 they are more musical then the LS 50 and have more bass. They are not quite as detailed but overall they are the better speaker
The new R is way better than any of the other monitors you are looking at and are more refined with a more precise soundstage, they have a similar level of detail as the LS 50 but the top end is a bit sweater overall.
Factor in deeper bass and a bigger sounstage makes them clearly the winner although they are the most expensive of all the speakers you are looking at and should sound fantastic with the Peachtree.
We have the new R series and the Reference and although they are similar the R series is still far superior in every way.
The take away from the design is how much smoother and better integrated the new R series is over the older R series.
We have in one sound room the R11 and the Reference 5, there is a strong familarity the R 11's sound fantastic for a $5k set of speakers but their is no mistaking the magic of the Reference 5 which go lower with greater authority, have a cleaner midrange, increased dynamics and btter overall clarity.
The tale of the tape is the R 11 weighs about 70 lbs the Ref 5 130 the difference in bafle construction, damping, driver construcion and crossover are clearly evident in the Ref 5.
That idea is what led me to the Uni-Q driver idea. I have to say the LS50 Wireless sounds great, and again, am just really loving the Nocturne look. I know so many people hate it for its Sci-Fi vibe, but it really is unique.
I went a bit off-track in my above question since I'm also looking for a living room setup. I certainly wouldn't put floor-standers at my desk.
Uni-Q is a 2 way for coherence not nearfield.I got a great deal on the 2K$ Omega Super Alnico single driver which enables me to listen 6 feet away in a bad condo room far better than I could with anything else .
Schubert you can absolutely listen to Kef's nearfield the fact that the tweeter is directly in the center of the midrange means that all frequencies arrive from the same point in space, also the quasi horn load of the shallow midrange's flair creates a very wide soundstage that helps create a very credible impression of muscians playing in space even if you listen to them close up.
When I say "near-field", I mean the average person sitting nearby, such as at an executive desk. At my desk there's a good 5' separation with the 32" monitor and probably 4' to my chair. That's at least how I placed them, angled in with the app set to "extra" bass.
Now the question is what's a good choice for the living room, at a reasonable cost? @audiotroy
