Quote: Lars, from time to time I get in touch with the developer of the rockbox port for HiFIMAN devices. BTW he lives in Moscow. I asure you that Rockbox works fine on HM-801 for already more than a year. Don't mislead fellow headfiers plz. The only real problem is with the dislays of the new batches of slims and even not all of them. I don't know anybody in Russia, who has even a slightest problem with Rockbox on HM-801, and there are plenty of 801 users here. So don't be afraid, ianmedium. Everything works just fine.
