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.

Hi Brianportugal,

The Silverlines are now actually being underutilized in my TV system, being driven by a NAD. The Harbeths are now relegated to a second system where I am running them with a Wadia 151 Powerdac since I sold the Musical Fidelity M3i that I'd previously been using with them.

Seikosha thank you. what would you mate the silverlines or Kef LS 50s with for vocals and jazz? I'd like to build toward a nice system. Any recommendations?

I am don't have much experience with hifi equipment and would like some help from you guys. As I have already mentioned in this thread, I am driving a pair of LS50s with a Nad D7050 amplifier. I am very happy with the sound but sometimes I believe that I may be straining the amp a bit too much. I am usually listening with the potentiometer levels between -15 and -10db. Is this forcing the amp too much? Am I putting my speakers at risk? Just for your info, the Nad D7050 is a 50w per channel at 4ohm amp.

How big is the room? What kind of volumes are we looking at?

At first blush, I think 50W might be a bit low for these monitors.

I have owned the LS50's since Feb 2013 in a second system.

I have used: a Naim Nait 5i-2 (60wpc) but really seems like
much more.

Edge i3 (100wpc into 8 ohm, 200wpc/4 ohm)

Simaudio i3.3DPX (100Wpc into an 8 ohm load and 200W into 4
ohms)
I have settled on the SimAudio. A great match with superb
drive and musicality. My unit has the built in DAC and Phono
and Balanced XLR options. Very nice piece of kit!

I would say the LS50's sound best with at least 150-250 of
high quality watts per channel into the 4 ohm load. (The
KEF's drop to 3.8 if I recall), and 100+ dampening factor.

If you decide to go with tubes I would plan on at least 60-
80 wpc of tube amplification. (Cary Audio SLI-80) you will
not regret feeding them with great amplification! My room is
12'x 18'x 8.5'.

Best to ya!
