Which op-amp for linkwitz transform?

[Hybrid fourdoor]

I am looking at the trueaudio.com linkwitz spreadsheet and it has the schematic, and it lists the passive components and all. But it doesn't say which op-amp to use.

I don't know much about op-amps, and looking through Digi-key I see about 10,000 op-amps in there. Which one should I use?

Thanks,
David

Any audio opamp of your flavor witch is unity gain stable. For instance a OPA627, OPA2604, AD811, etc etc. See other topics on opamp flavor.

Any 8 pin dual op-amp. TL-072 is used on Rod Elliot's board.
