I agree, I have heard the Zenith and the SE, both are excellent, but the SE a step up. I bought the cooking version before the SE came out, but the earlier version is still excellent. I think they are easy to use and of very high quality. The opposition, Melco and Aurender come to mind are great too, but innuos are cheaper, sound great and the company provide excellent support if you do have problems, at least here in the UK.
Limniscate, what DAC do you use or have you tried with the SE. I use the Ayre QB9 and am happy with it, but I would like to know your experience.
