With the LS50, I began to understand what the criteria for universal praise was. Evenness. It was remarkably even from top to bottom. Tonality of instruments was spot-on, and that tonality remained all throughout the range. Note that the range was limited and truncated even further when presented with complex materials. Orchestral music? Forget it. It simply gets overwhelmed with the monstrosity of frequencies and mumbles indistinctly. But jazz vocals? TO DIE FOR! This is the ultimate for those who want the tangible vocalist in front of you, singing JUST FOR YOU. Same applies to small bands and chamber music. It is worth every penny. Just count the number of players before you press start.
Kef R300 - These are markedly different sounding from the famous LS50. They do have more bass extension, but it's not controlled. This kind of pungeant bass lends itself a darker character. Mid and treble are still clean and detailed, but get obscured when pushed hard. One thing I have to say though, when listening to opera, ALL of the Kef speakers auditioned so far have excelled at locking onto that voice while the singer is running from mic to mic behind the orchestra that is going nuts. My conclusion is that they are exceptional at focusing and complexity which is a huge plus.
Kef Blade - First impression. Earthly beauty. Contrary to their extreme styling the unadorned sound doesn't overwhelm you. Instead, the naturalness makes you wonder if the sound is really coming out of those sculptures. I now understand that tonality is about faithfulness to the source. What you are reproducing is the recording, not the instruments. In my case, I'm recreating digital recordings that do not capture the live instruments well. This is bloody difficult. The Blade's reproduce faithfully, then. They stay true to the source. Whether that sounds natural to you or not, is entirely up to you. Show me yours and I will show you mine. Funny how the R300 tries to sound bigger with boomy bass. It's like looking at a blowfish expand itself. The Blades can only chuckle at such immaturity.
Summed up my listening to the R300/LS50. I really wanted to like the 300's as i could get close to the LS50 but with bass. Didn't turn out that way. Very nice speaker, and I think I could live with either one. I like the slightly darker character, but things got a little sloppy with more hectic music.
Kef LS50 - I kept going back to see if there is any way possible to use these as I need. It soon became about what THEY need. They needed a smaller room to keep from straining. They needed an awesome amplifier to do them justice. They needed only half of my music collection to play properly. But what about my needs?
