OPA2134 or OPA2604

[JoeBob]

Well, I've made a preamp to use either of these opamps (used a chip socket) and was wondering what peoples thoughts were on these two, any preferances between the two? I'm planning on sticking one and not changing, since I probably can't tell the difference (am used to very crappy equipment), but was wondering if any could tell the differences and if either one was "better" in any ways.

I would guess that it's not a coincidence but just in case it is:
somebody else just asked the same question at headwize:
http://headwize.powerpill.org/ubb/showpage5.php?fnum=3&tid=2042&fdays=20&stime=0

Some of those guys really know their opamps.

Actually, if you mean you think it was me, it wasn't. Must be one of those wonderfull coincidences.

That was my first thought (that it was you), but then I checked the profile and it's somebody in Chicago, I think.

Thanks for the reply though, I checked it out and noticed the comment on the OPA2604 needing more juice, so I checked out the spec sheet at TI, and it seems like it'll like anything from +/-15V to +/-24V, while the OPA2134 only likes up to +/-18V (pretty close to the -17V of my power suply), so I think I'll feel safer going with the OPA2604 regardless. Thanks again.

Joebob,

or try the OPA2107. It sound a lot better than the OPA2604
