RE: KEF LS50 disappointment :(

The piont most forget is that some people may not like the sound every says sounds good to them?.. Secondly I have upgraded my HIFI system many a time. Only to take it to several shops and finally found out it was room acoustics all along!! Each shop i went to with the equipment sound just fine, but went home set it back up & just sounded horrible...

I got a pair of Bostoin acoustics M340 & now my system has never sounded better! Yes I did the hard work of buying & moving speakers to audition at home.  Immedialately I heard the first few seconds I said this is it.

Always audition at home simples!!

So to summarise, the LS50 is a fantastic speaker but it needs care: good stands, good positioning, decent amplification.  To the OP who's mates said their Ford Fiesta produces more bass, well that just shows how dumb you and your friends are.  If you want masses of sub bass, buy a sub or get Cerwin Vega speakers!  The LS50 is for music lovers who like a natural, realistic and accurate sound that you can enjoy for hours on end.

 

+1

Give them a good heavy stand, let's say Dreadnoughts (fill them 3/4 with birdsand or Atabites) or similar good stand. Toe them in a little bit:; less then 10 degrees. Give them some space, and with a decent amp they will sound fantastic. If they sound dull, shrill, not open, harsh etc etc...there's something wrong with the set-up o/w system.

Define "proper bass".

I want to hear and feel the low notes of the keyboard on Genesis Firth of Fifth, the heartbeat on DSOTM, The deep notes on Tuung Soup and the bass notes of the organ rumbling through Saint Saens organ symphony. None of those are heard properly with a small standmount speaker that has no sub.

Proper bass.

And this is it. The definition of 'proper bass' is open to interpretation, and also personal preference. 

Other than depth and intensity, there's also detail in bass too. When properly set up, this is what the LS50s can do that many others can't - they allow you to hear real texture in bass, which larger speakers generally can't do (not on the same sort of budget anyway). ATC's SCM11 and SCM19 would also be examples of speakers that can reproduce subtleties in the bass region.

By the sounds of it, you're after a larger speaker, and one that can shift a hell of a lot more air than a 5" driver. I would suggest looking at Monitor Audio's outgoing RX2 or their replacements, the Silver 2. And if you're talking about using a subwoofer with them for accurate music reproduction, that's a whole other kettle of fish...

 

Bass "texture" is the higher harmonics being more obvious because a smaller speaker is incapable of fully reproducing the fundamental low note at the correct amplitude.

I agree, but this texture is still generally dealt with by the mid/bass driver, and bass texture is still something that many speakers can't convey. My statement (and previous statements) about good bass texture and capturing minute pitch changes still stands.

                 I feel the LS50's produce a more balanced bass note, without dominating the whole presentation.

If you want proper bass with these speakers a sub is required. They roll off fairly quickly after about 80Hz.

Hi TrevC

For lower and deeper bass (while retaining the LS50's) a sub is the way to go.

All the best

RE: KEF LS50 disappointment :(

So, I am interested in keeping the experiment going at home.

I have been playing the LS50 with the D 3020 over the past few days. Sounds is good, but I want to see if it can be improved with more power.

The amps that I am currently interested in testing (the ones that seems to fit my needs):

1. Bel Canto C5i

2. Simaudio 340i

3. HK 990

4. Rotel RA-1570

All integrated above come with phono / dac, and other than the Bel Canto, they are all rather powerful. 100W+

Form factor the Bel Canto is most interesting for me, but it might not be as powerful as I'd like.

Both the Bel Canto and the SimAudio don't offer tone management (which would be nice). There's also no connector between the pre/power, so it won't be as easy integrating a sub with highpass filter with these two.

The HK990 seems to offer everything that I would possibly need (including auto EQ), if only it wasn't SO big. 

Would love to hear some opinion about this. I guess that I can always use speaker level input when connecting a sub, and I can get a way without tone control. However, if audio wise (phono input / dac / power) the HK990 / Rotel, than I guess that I should give them a try first.

RE: KEF LS50 disappointment :(

I can't speak for the rest, but the Rotel 1570 is a cracking amp, and should show the NAD a clean pair of heels with the LS50s. Do let us know how you get on Smile

RE: KEF LS50 disappointment :(

@tk1111 have you considered the NAD 356BEE DAC?  Its got a oodles of power and a really good built in DAC.  In the UK it can be had for £700.

 

I'm in the market for a DAC-enabled amp for my LS50s right now and the NAD looks like a good bet at the moment.

The problem that I am having with the NAD is that from what I understand you need reach the back of the amp to switch between the DAC and the phono.

@tk1111 Curious as to what happened?  Did you find the ideal amplifier for your LS50s?

RE: KEF LS50 disappointment :(

I first bought the Arcam FMJ amplifier A19 along with the Kef LS 50 speakers using Chord Chameleon connects. I first auditioned the Kef R300’s with the FMJ. The R300’s are sharp, energetic, very detailed, with a kind of slightly bouncy bass, but a kind of quick, lightweight sound that I suspect may hurt my ears after a few hours playing. This is not a criticism of them because they do sound great, just not for me. These are speakers I imagine I would have bought in my twenties.
After a play through of my favourite music I changed to the Kef’s. Now in my late thirties, these speakers sound so right. The difference in tone, treble and bass was immediate. The bass really stands out for me. It is tight and controlled and keeps it’s pace with the music. Vocals sound sublime and throw themselves outward. The detailing is superb also. Listening to Hey you by Pink Floyd, I could hear the little inflection’s Of David Gilmour’s gravelly voice really come through effectively. Fleetwood Macs Oh Daddy was charged with emotion and the vocals merge well with the acoustic guitar, but strangely feel spaced perfectly within the mix.
I now listen to these speakers for hours on end with no ear ache. They are a well balanced speaker, not too bright, an even, refined sound, without at all sounding boring. A mature energy is what I feel with these when I listen to music across the board.
After three months of use (and I listen to them every day), they continue to surprise me with their lush sound. Listening to Goldfrapp’s Annabel has enourmous appeal. Her voice and the snap of consonants at the beginning and end of her dark, musical sentences are hauntingly beautiful to listen to. And this disc is spinning in a 12 year old Marantz 6000 cd player. Which brings me to the Naim cd5si.
Careful listening between the two shows subtle, but noticeable results. The undertones of Goldfrapp’s Annabel feel more distinct and thrown forward into the mix. The same can be said of the Doors, Riders on the storm. The bass drives the song while the ghostly echoes of Jim Morrison’s lyrics are that little bit more apparent in the Naim. The sound of this player definitely feels bigger and spacious, in an ever so subtle, but noticeable way. To my ears it sounds great with the Arcam FMJ and LS 50’s. These speakers have a direct, focused and open sound, very earthly and warm. It’s as if the two are spiritually connected, like soul mates. I love them. The build themselves is solid and they look and feel expensive, The highly polished black against the copper speakers are a beautiful compliment. The official rose gold colour is another way of saying they are copper coloured, but they had to say rose gold because of the 50th anniversary theme didn’t they. I don’t think their modern look is out of place in an a more traditional setting either.
One thing I have noticed with this system, or with any system for that matter is that a poor recorded album will show its weaknesses with this setup more than it would a cheaper system. I cannot recommend enough.

Beautiful, dynamic, detailed and open sound, Solid and controlled bass, These speakers seem spiritually connected, like soul mates

Ditto what you say about poor quality recordings.  I have really noticed this too.

RE: KEF LS50 disappointment :(

I think the problem here is the amp you have them pared with, the size of the room you have them in and maybe a lack of a decent stand...are you using stands?

to quote What HiFi

"Given a little space to breathe and mounted on a pair of solid stands these monitors sound terrific. The first thing that strikes us is the quality of the bass performance"

So if you think that your system is lacking bass...this is probably why. Under negatives in the What HiFi review, they list demanding on partnering hardware. I'm not sure about your amps spec, but this might be an issue.

If I were you, I would try and find a delaer that has them partnered up to an appropriate system in a room where they sound incredible. You can then work backwards.

Borrow a mates amp, put them in a bigger room, see if you can lay your hands on some stands...and try every combo until something clicks.

I think really the solution is to take them back and get a speaker that is ideally suited to smaller rooms and can produce the bass you like. I have small room and have a pair of Wharfedale 9.2's (the 9.1's bigger brother). The bass is BIG but tight even at low volumes and it isn't a fussy speaker when it comes to position or stand pairing. You can pick these up cheap now to
