I honestly didn't know the name existed until I saw your (lovely) pictures and description (and family link) of the buds. I don't normally buy headgear on a whim (except maybe the NichHCK EB2S) without doing some research. But If you are calling these warm, but clear and accurate in the resoltution, that is all I need to hear. I know you are sensitive to overbaked presence region, and you didn't mention this. I have yet to hear a good bud that isn't, so really I am sort of used to it by now though.
Are all of those models still available? Is that why you are having a hard time getting them? Or is it simply where you live that is making it difficult? Or is it that you are alluding to the DR-09 sucking, and that the DR-08 and Green Bull might suck too, so nobody is stocking them?
Other than this thread, there really is no place to go to learn here in the US about the different brands of earbuds. As we have discussed in the past, doing a search does

good, and they aren't marketed (and a lot of times) not even reviewed here very well, if at all.
Anyhow, enjoy your new toy, and let us know your thoughts as you get some time on them?!
