<p>Cheaper perhaps in parts, not counting assembly and board space.
And the OPA1678 is only about $0.25 in quantity. It's become my
go-to audio op amp for all round good specs.</p>
<p>There's also the RC4560 which is about same price as the 5532.<br>

the OPA1678 has a higher drive current than the 5532, but
using both of the pair of a 5532 in parallel works out
cheaper than half a OPA1678 per channel provided you don’t
mind the 4 times quiescent current (2* per opamp and 2
opamps).
