Op-amp Replacement for JRC. Hey all - I've just taken my first step into the much larger world of audiophilia not a very attractive name, really by purchasing a nice sound card for my computer - it's an HT Omega Claro Halo.
The documentation says that it is meant to have the op-amps switched out as the stock ones are low-end, but of course I'm pretty lost in this situation. It says the current ones are JRC - which ones can I even look at that would replace that one? And I know it's all subjective, but can anyone recommend a good one that would work in this implementation?
Thanks a lot! Find More Posts by raudio Are the current opamps DIP-8 or surface mount? What voltage is available at the power pins of the opamps? Hmmm, I'm not sure what the difference between DIP-8 and surface mount is. I know that they're designed specifically to be popped in and out for experimentation, so I won't need to wrestle with getting them in and out.
They look like all the schematics, but unfortunately that probably doesn't help you Again, I'm not sure about the voltage, but it's a PCI card so I believe it's max voltage would be about 5v - that would jive with the current op-amps and their low voltages. How would these things affect my choices? What should I be looking for? The best part about it is the support for the card is really great, so once I get a few op-amps I'm thinking about I can e-mail them to make sure they're compatible.
OK, socketed means they're DIP If you're up to soldering surface mount chips to adaptors if you're unsure, that's a no, but maybe you know some-one who can also consider AD Well awesome! Thanks so much for all the replies.
It looks like I've got a good list of options. Now can anyone tell me where I can read about the sonic qualities of the different chips? If it is all subjective, is there any way to know which one I would prefer without purchasing them? Thanks again! Attached Images image BB code is On. Smilies are On. Forum Rules. All times are GMT.
