[Lowfer] Sound card recommendation

[Dave Brown]

Looking for recommendations and/or suggestions for an external  (USB 
preferred)  sound card for use with digital modes and SDR experiments, 
etc.
Must have line level input capability and at least two input channels 
(L and R stereo most usual I guess- more inputs acceptable!).
Prefer 192kHz max sampling rate with option to switch to selected 
lower rates-ideally in hardware. Any other suggestions re desirable 
features welcome.
