Hi, I'm designing a new product where headphone outputs are driven by an op-amp.
Now I'm looking for a new op-amp to replace the NJM4556. This op-amp has a very clear top-end but is a bit wimpy in the bass.
The op-amp must be a dual type in an SOIC8 package. It must work with supplies from +-5V to +-10V. At the moment I'm just curious what is out there and what your experience is with different headphone outputs. The price point of the final product isn't yet 100% set, so I'm happy to test out op-amps in different price grades.
