Quite similar to Intellijel Audio Interface II, available, cheaper and less HP: 4ms Listen IO (I've been using it for live use for 3 years, and with great satisfaction).
These two modules which are less known, with several inputs/outputs, but of which one says a lot of good: Bubblesound Instruments Booster Stage and Reducer (I have the Booster, perfect to make enter synthesizers or drum machines for example).
Credible and affordable solution: Erica Synths Pico Input and Output.
More sophisticated, more expensive, and probably at the top of the podium: Joranalogue Audio Design Receive 2 and Transmit 2, or the superb ACL Audio Interface.
If you want to multitrack in a software (Logic, Ableton, etc.), you'll have to include the Expert Sleepers solutions: ES-8, ES-9.
