Default AD and BB, but why not Elantec?

Usually all discussion on op amps for audio centers around a
bunch of well proven ones from BB/TI, AD and to some extent NS.
However, also companies like Elantec and Maxim have a number
of op amps that, at least on paper, seem to be interesting
competitors, but those are seldom if ever mentioned. Searchin
the forum, I did find quite a number of post about people using
or suggesting Elantec, but there are never any discussion of
their performance. Why is this? Are these brands simply not
up to it to compete or what is the reason?

Default Addendum

I did a search over at Audioasylum and there I did find a few,
not many though, reports on experiences with Elantec op amps
and buffers. It seems most of these were quite positive, which
makes wonder even more why they are so seldom mentioned
in discusssions here.

I was thinking of, for instance, EL2044 and the dual and quad
versions of it, and the CFB video driver EL2099 which might
potentially be a good buffer.

Elantec or Intersil nowadays isn't hip!

Everybody (including I) nags about OPA627 and AD8610 and hate NE5534.

There are loads of useful opamps out there.

Default Horses for courses...

When I think Elantec, I think video.
When I think maxim, I think switches.
When you're good at one thing, it isn't so easy to get taken seriously for something else.

Default Prejudice and fashion

I am continually amazed that a group of people who one would assume should be able to assess a product in purely rational terms should have developed such irrational prejudices.

Who cares what is "hip", the facts are that the NE5534 has some qualities that are hard to beat, in the right circumstances.

See the likes of D. Self's Site and http://tangentsoft.net/audio/opamps.html for some interesting anaysis.

Default Re: Addendum

I'll go out on a limb and propose my theory, based on a few years of observation of audio DIY discussions.

"The more liberal a company's sampling policy is, the more likely their devices become popular to the DIY community: get used, talked about, experimented with, etc."

No, don't think so. Saying that a '553x is good does qualify though.....regardless of price or who makes it. Can't see any reason for using them.

Have seen circuits designed with them that other op-amps will not work in.......ones with inputs near the negative rail. Yeah, you guessed it.....British hi-fi.........

Those guys over there must not get out much either. At least the Swedes have an excuse........[joke]
