Indigo sound card by Echo

[RASTABT]

The Indigo is a Type II CardBus PCMCIA add-on sound card that can be installed in one of the card slots in your current notebook. Once the Indigo is installed, you will have true 24-bit, 96kHz audio, with high quality digital to analog converters and a Motorola DSP. Best of all, once you plug in your headphones, you hear beautiful silence, with no hissing or buzzing to detract from the audio quality.

Nice one... although most audio pros will still opt for the Echo Layla24 laptop extension adapter solution (works with the Mona, too).

That is if they already use an Echo Audio soundcard.
