Haven't used this in a while so I'll throw it up here for sale for $60 shipped to the continental US.
CopyPasta: 4 x 4 24-bit/96kHz full-duplex audio interface
4x4 analog I/O
Need a great sounding audio interface without digital I/O? The Delta 44 offers the same features and high performance as the Delta 66, but is designed for the user who does not require digital I/O. And like its big brother, the Delta 44ís breakout box handles four balanced/unbalanced, +4dBu or -10dBV signal level analog inputs and outputs. You get the same 24-bit/96kHz fidelity, industry-standard driver support and bulletproof operation as is found across the entire Delta family.
Comes with a serial cable so it's plug and play. These are very highly rated and stable cards. Still supported by M-Audio for the latest PC and MAC os's. Stock photo, obviously. The box is a bit scratched up with some small rust spots but it is only cosmetic.
