I think that depends on what you're looking for, really. Unfortunately I can't compare to OMZ as I haven't heard it. There are those that have equated OMZ with zapped Zhaolu (which I've owned) as far as SQ goes, not signature. Zapfiltered Opus handily beats zapped Zhaolu to my ears.
Abe, when mine gets finished, you are welcome to try it out for a couple of weeks. Mind you it may be a little while before it gets completed
