I bought a Lavry DA10 some months ago and have been very pleased with it. It is not as analytic as the Benchmark, but lacks the sterility (though that is really too harsh a word for the Benchmark.)
I find the Lavry has good depth and resolution with very natural sounding highs. I play a fair amount of acoustic material and find myself sensitive to any stridency in a system. I think it is the lack of that and the ease with which the Lavry presents music that makes it so appealing. It also has a wide dynamic range and maintains it's excellent sound during softer passages.
As far as the Altman, I haven't had any exposure to it.
