OPA1656: High-Performance TI OPA134 vs. (Normally one would probably point to LM4562 as being the best compromise, but I think the Quiescent Current of 10mA is very high) OPA1656 has even lover distortion. The LMV358 is good for a little signal generator, but falls short of high-fidelity audio. Misc. I like opamp rolling, but the dac x6 opamp socket is for the i/v section of the dac and the power supply is very limit(3 parallel icl7660 generating a negative rail for the tpa6120+op275 and the opa2134). OPA2134 op-amp obsolete? NE5532 is dual channel opamp, so you can try few of these: opa2134, LM4562, opa1642, opa1656 without burning too much money on rolling opmaps. I can vouch for the OPA2134.
