Not familiar with Bloom, but I have the Blukac's. I've not had a chance to use that case much lately, but when I was playing around with it, I found it mildly interesting, and am hoping the expander will open it up more. The expander comes in two parts (with no directions in the box, btw), with one snapping onto the back of the EP, increasing its physical depth, and another module that increases the hp by 4. It is supposed to add v/oct, which should make it shine, but beforehand you have to upgrade the firmware, requiring an online search to do so. I have not had time to do so, so I can't comment on the expander yet. I did notice that having the expander extension on the back of the module does not seem to affect the original operation, so I've manually installed it (hopefully correctly!) and will eventually get around to upgrading the firmware. You need a SanDisk, btw, not provided, to upgrade. Until then, I'll just play around a bit with the original EP. It does what it says, but I don't think I've used it enough to give an opinion on it.
