He visto que está a punto de salir en España el interfaz e-mu 0404 usb 2.0
Las características técnicas son impresionantes por un precio total de unos 200 €. Tiene chips independientes AD y DA, de fabricación japonesa. He descargado las especificaciones de estos chips y se corresponden plenamente a lo que dice la e-mu. Es una pasada.
Incluyo la parrafada:
General
Sample Rates: 44.1, 48, 88.2, 96, 176.4, 192kHz from internal crystal (no sample rate conversion)

USB 2.0 Hi-Speed
- Full 24-bit resolution at all sample rates
- 4in/4 out channels from 44.1-96kHz
- 2 in/2 out channels from 176.4-192kHz
Zero-latency direct hardware monitoring (disabled at 176.4-192kHz)
ASIO2, WDM, MME - AC3 and DTS Passthru protocols supported
Anti-Pop speaker protection minimizes noise during power on/off
