The Continuum is .5dB per attenuator step (I think that the Capri is also), but it takes a setting over 30 to start rising above the abient noise with my speakers rated in the 90-93dB sensitivity range.
I generally listen from a setting as low as 50 (reading by myself, sitting close to the speaker with low ambiant noise) and as high as 79.5 or even just over 80 (trying to knock myself out of the listening position with MTT's excellent Mahler 6th). With a super efficient speaker I suspect that I'd listen around 20 and my upper range might be 29 (BTW, those are step setting readings, not dB). I still think that the loudness refinement would be granular enough, but you'd definitely want to try.
Surely, no one owning horns is going to go buy a Continuum 500, but if you already had one laying around, then it might actually work pretty well.
