Mod your Beresford 7520

[apmusson]

AD826, not sure if this one will behave in the 7520, if it does it should be very good.

AD8620 has its fans, its similar to AD8066 but behaves more in a wider range of circuits, some find it lacks bottom end
Last time I used one of these adding a CRD from output to supply pin with worse PSRR greatly improved it

I've tried dozens of op-amps, not in this dac though

I'm considering trying either one of the 2 you mention above or maybe even a couple of OPA627s on a brown dog adaptor. I am currently using a THS4032 (headphone) with a 4562 (fixed output). Headphones are my primary listening equipment and I read that the 627s are an excellent headphone driver.

Any comments? Would the browndog adaptor fit? Am I out of my mind (the 4032 is superb already)?
