The dx100 is a pig compared to HDP r10. Even the battery is not the same. I ! Not downing the dx100 owners but anyone here that had both sold the dx100. As I did. And I basso with the firmware chNGes all,the time and never bothering to just stip the software down to just a palaver as hibino did . Right after it's release tells be the I basso camp has feature mined group and the hibino was all about the sound. It's 2 years later and I can afford to buy what ever I want . I still own the hibino. And I sold the AK120. Yes the ak120 was small and worked much better than the hibino . But the sound lacked I lmpact and micro detail. Line out did sound better though. So maybe what VINNY at wine audio was doing was a really good idea. . I own a I basso bal portible amp. It's pretty good. But no DAPS for me , not from them. They have the resources to A make a great product but truly lack the follow up to perfection . Now let the bashing begin. And yes my English stinks. But my hearing is fine LOL.
