Lurking here, I see you didn't get any replies.  Maybe I can start the
ball rolling.

I own the UA-1A and am very happy with it.  Cheap (£75 when it first
came out), no configuration apart from activating USB audio in the kernel.

I did struggle with the quality of audio produced

But those issues were not related to the UA-1A itself, I merely had to
ensure the source volume wasn't too high.  Ecasound is great,
ecasignalview allows you to set this correctly in realtime.

| - What is the "native" capture mode of these units?

16 bit, 44.1kHz.  Not adjustable.

| - How can I control record level on these units?

Not possible on the device.  You need to be able to do this upstream,
otherwise clipping will be a problem.

|   If there are no knobs, can the level be set with software?

No, no mixer access is available.

Sound quality is good enough for me (a consumer).

HTH, Tim
