KEF LS50

Don't post often here but thought I would let you all know I stumbled on a pretty amazing performer in this little monitor.

I would say the midrange is on par with my Harbeth 40.1, treble has a tad more leading edge bite than the best soft dome but its a really good top end that never gets nasty. Dynamically they are performing way better than they should. I'm betting they would compete with the new 30.1 sonically, just a guess.

Have them running with 20X price electronics in a small office and they are not outclassed in any way. Made me want to keep throwing my best gear with them they sounded so good.

If you are in the market grab a pair, you will not regret. Saw two pair this morning for sale for around 1K, I can't think of anything in 20 years offering this much performance for 1K. You could build a world class non-full range sound around these.

IMO, I think that the NAD is underpowered for use with the KEFs. If you listen to dynamic music at loud levels.

I would not want to push those speakers to 85+ db as you may start to hear compression and distortion at the higher levels. If that happens turn the volume down ASAP!

It is better to have some headroom in your amp. More amp will not hurt a speaker. The opposite, however, will.

I purchased the LS50's on Amazon in case I felt the need to return them at some point. So far I only have maybe 30 hours on them but they sound rather bright and lacking in weight or authority. I know they're not floor standers but given the reviews and other much more expensive monitors I've heard, I was expecting more.

Maybe the room isn't well suited since there's no back wall, but a back alcove. Also the 36" stands are probably too high.

I'm using Cary Audio Cinema 11 preamp and Cinema 5 amps to drive. If things don't improve dramatically they'll go back to Amazon in a couple weeks. Almost painful to listen to most material on at the moment.

Never seen these displayed or demoed with a tall stand. IME, 22-28" is common. I am using 24" stands and they are fantastic! Weight, depth, 3 dimensional. They really sing in my set up.

Play around with your positioning and let them run-in for at least a week with some dynamic music and high SPL.

Smaller monitors in general often tend to do best on shorter stands where floor can reinforce bass a tad more than otherwise.

I've heard the KEFs. I would tend towards using shorter stands in all but perhaps the smallest rooms.

Good points - though I don't want to invest in shorter stands til I know these are keepers. I'm it would help having them at or below ear level.

I'm seeing more of the potential of these - especially since I went back to the older darker Purist Audio Museaus IC's instead of the newer livelier ones. Gives some much needed depth and gravitas.

But I'm pretty sure I'll find their lively revealing sound isn't what I'm ultimately looking for - but for those that are these are already obviously very capable for the price. But with more burn-in and once my ultra sweet Cary 98L preamp arrives, things could get interesting.
