beryllium vs diamond


Hi guys, today's technology has brought us a new type of tweeter made of diamond or beryllium. Do you know what are the strengths and weaknesses of diamond vs beryllium? Which one is the more expensive? Has today's dome tweeter better resolving power than the venerable electrostat? Jim Thiel once said that dynamic designs will be getting better all the time and will probably surpass electrostatic designs.

Sorry Sciencop wonder how many people here own or have owned speakers with diamond or beryilium drivers?

We have had the Polymer Audio Research MKXS in the past.

We also have the Paradigm Personas on display currently.

So yeah we have actual experience.

Dear Kost,

How do you explain why an amplifier sounds bright, Stereophile couldn’t and or why an amplifier sounds dull?

If you look at published frequency response graphs of almost any modern amplifier they are flat from 20hz-20khz.

And yes Kost, unlike you we have had these loudspeakers in our store, we lived with them and found out what their intrinsic characteristics were and or are.

Kost you don’t need an engineering degree or an electrical degree to understand what sounds good and what doesn’t.

We talked about cars before, if a Ferrari is driving at 60 and a Pinto is driving at 60 the spec is the same, does that mean the cars drive the same?

On the same token if I take a Ferrari put 82 octane gass and deflat the tires at different pressures accross the board does it drive like the manufacturer intended? According to spec or not to spec?

We live in a world where certain things must be experienced and their is not enough measurement criteria to determine why something sounds good.

You are looking for empiracal data when there is none, that can prove that one amplifier sounds right on a particular set of speakers but people with ears know it when they hear it.

Last point Kost why do so many people like records over digital, digital has no noise much greater dynamic range, doesn’t degrade, has perfect frequency response.

Or tubes?

A tube amplifier has poor damping, is noisy, wears out, has much greater noise floor, yet why do so many people prefer the sound of at tube amplifier?

Good luck Kost.
