beryllium vs diamond

Audio is all about comparing and shootout. I will ask for a shootout in the beginning of 2016. I will invite B&W and Focal. I hope they will accept the invitation.

Bo, you should get the Magico's and Vandersteens in that shootout. Carbon needs to be in this discussion. Again, we all know it's not totally about the material, it's about the implementation AND material. Carbon is very special in audio right now and depending on WHICH carbon fiber you are using, you will hear something different. There are so many new technologies that designers can use these days, that they are really making huge strides. Probably more than at any other time in audio history. Most older speaker technologies just don't sound as good as the new ones implemented properly. Regardless of WHAT type of sound we each like, all of us seem to love our newer speakers made from diamond, beryllium or carbon fiber. Someone moved the cheese and the landscape is changing with it.

Another example: Many highend speakers use Thiel&Partner ceramic units. I sold Avalon for over 6 years if time, even to some of my best friends.

These speakers have in common that they often can create a wide and deep stage. But......when you listen to intimate acoustic concerts in real you will hear how small voices and instruments are in proportion. I call it intimate sound.

When you play this kind of music on speakers with Thiel&Partner units you will hear that instruments and voices become bigger than in real.

The other thing you often audition is that with a cello or double bass it colours it a little. I call this: a mjeah. It makes these instruments sounds thicker.

In the beginning of this year we visited an audio show and many new speakers overthere used paper. I thought; What the F....It reminds me of audio when I started in 1998.

The demos were so poor, these days we have much better materials. I also don't understand why B&W is using paper in some of their speakers these days.

Compared to 1998 when I started in audio, the quality of materials has improved a lot. Often they still use older materials.

Schubert,,These Yamaha NS-5000's sound D$MN G$$D!...even through headphones!! Even on YouTube!! Sounds like High-End to my ears!!

And they have even more YouTube Videos on these All New Yamaha NS-5000's !...Man..I love this hobby!! Thank You Yamaha!!

I so enjoy "the older material" Skaaning midrange drivers used in my loudspeakers. I suspect (with tongue firmly in cheek) the implementation must overcome their polypropylene pedigree.

Keeping to topic, my loudspeakers implement Accuton diamond tweeters (BD30). Years back I owned loudspeakers using the Accuton BD20. To me, the Accuton diamond membrane sonic character doesn't stand out in the sense of immediately calling attention to itself in a "oh, wow!" kind of way. Given the cost, my initial expectation was that it would. It's positive attributes are, really, quite subtle. It is as if the treble content of music simply flows. Complex treble content from multiple instruments retains the separateness of the individual instruments to an extent I've not heard with ceramic, ribbon, or soft dome tweeters. Clarity of ceramic and ribbons, but with an ease that is hard to describe.

I've never heard loudspeakers with beryllium tweeters, so cannot offer an opinion on similarities/differences versus diamond membrane.
