upgrade Dynaudio Special 40 to Kef Reference 1

Kren’s point about KEF Providing more consistent sound from different listening points than most including Dynaudio rings true from my experience with Dynaudio Contour monitors versus KEF ls50. The Dynaudios were very good but seemed to require more care in exact positioning as well. Dispersion with the KEF UniQ driver seems top notch. I often listen from my desk located between the two speakers and the KEF ls50s retain their character particularly well even there.

dynaudio require power power power and more power big transformers ,heavy amps:) this hegel offers not so much, Yamaha AS3000 looks nice,but again no real power
If you get decent powerfull amp,the sound will be as listening gryphon and big speakers in your room:)
Not sure abaut your bugdet ,but there is big krell fbi for sale
I think even krell s550i will outperform hegel and yamaha and will make your special forty sing

There is no evidence that the kef reference one is perfect or better. 
Kef came out with the LS50 which is much cheaper than ref 1 yet they say the LS50 is one of the best. Every speaker on the market is "the best". There are no bad speakers. its a hoax 

I do think it’s strange that when you go to the Kef website, they list the blades and the LS50 as their flagship lines, and the ref line and everything else under hifi lines. 
At least it was that way up until a few weeks ago haven’t checked recently. 
Does seem odd that they’d sell ref 1 at many times the cost of “flagship” LS50. Odd marketing choice on their part to group things that way. 
Note I’m not comparing ref1 to LS50 myself as I don’t really have an opinion. My point only that kef’s marketing groupings are curious 

The ls50’s are one of the best for it’s size and cost.

C’mon kenjit its not so hard to understand that no two things are created exactly equal.

If one must measure speakers relative to others, ability to deliver flat clean bass down to 20hz in a particular room is a reasonable way to measure. Speakers that can do it well ( along with doing all the rest well) in a larger room are clearly better.

Size matters with speakers. As does quality. Speakers must work hard to deliver full range sound in larger rooms.

Ohm Speakers are a good model of this. Room size mostly determines which model is best, how big, and the cost. In a smaller room a larger more expensive model is not necessarily better in that it will deliver too much bass but otherwise the design and sound is similar.

It’s a most scaleable design.
