Class AB and Class D market share?

RiskCord · 4th September 2009, 06:46 PM

Short non-technical question: Does anybody has any information or estimate on how Class D amplifiers are performing on market in relation to Class AB amplifiers?

luka · 5th September 2009, 06:18 AM

depends on model to model, Class D can be as good as AB and AB can be as bad as D if you know what I mean

Let numbers do the talking:

numbers are nothing, I can tell you that only the sound that goes out of speaker is valid, and many will tell you "analog is warmer", by warmer meaning sound... I am not a fan of AB, but they could have a point there

Eh... market share has nothing to do with technical performance of product e.g. iPod has largest market share, if that's what TS wanted to know.

Yes, as wwenze says, I'm not talking about performance comparision, but simple figures like the ratio between the number of Class D amplifiers that have been sold last year and the number of Class B, AB...

The reason for asking this is that I have the impression (I might be wrong, of course) that Class D are still not widely known and even less widely accepted. Of course most of you here are as familliar with Class D amps as with your own hands (ok, I might be exaggerating

) but for what I've experience in other "technical circles" it is not the case. Most people I have surveyed have "kinda heard" something about Class D, they know it is a switched amplifier and they thing that D stands for digital... I have checked on internet and I havent found any convincing figures.

Anyway, the topic keeps open...

and what is that ratio? and what market you include, home, PA, car, what?

I like class d,low output impedence,its good for low sensitivity loudspeaker.
just like Luka said: depends on model to model

I don't know the exact numbers, but the original question isn't very specific either.
When batery-operated devices are considered, like mobile phones, than class D wins. In PA systems class G/H and switched/linear hybrids are doing surpisingly well in terms of sales.
In home hi-fi class AB is still having most of the market and it is questionable if there is much point in having, say, a 25W class D amplifier in a home stereo.
But I've seen new dirty class B amplifiers in applications, where class D would perform much better and be way cheaper, that's still a matter of time and market inertia.

...and if you include TVs, mini stereos, car radios, Class D should predominate by now.

My diy Class D monoblocks beat all the Class ABs I've ever owned by a wide margin.

When will people learn that Class D is analog, not digital?
