I was wondering if this would be a good alternative to replace the wall-wart of a Squeezebox Duet. Anybody here who has some experience with this power supply.

It looks a little complicated to me. I'd just go with the good old LM317 and LM337. There was a document around with a study on optimum capacitors for those regulators, but i don't remember where it was (i'm sure people here know it though). If no one else remembers it i'll look around for it.

Yes LM 317 / 337 are old but not good. Discret regulation sounds 10 times better.
Did you built it properly? I have a hard time to believe that the NE5532 would die if you had a proper supply voltage. I can see the low margin though.Hello!
First post here!
I've built this power supply for an active filter: big noise at négative output rail! And with +/- 15Vac in, the poor NE 5532 will die quickly with no load: select +/-24V OPAmp like OPA2604.
