<p>What about just using an op amp with higher current capabilities,
like<br>
</p>
<p>TS922: Rail-to-rail input and output, Low noise: 9 nV/√Hz, High
output current: 80 mA (able to drive 32 Ω loads)</p>
<p>or for split rails maybe the OPA2990?<br>
</p>
<p>For line level outputs that should also cope with headphones (as
opposed to dedicated hp outs) I've been using OPA1678 which I
think can output 50mA. Have I been doin' it wrong?<br>
