Does anyone have any firmware for the Studio? Mine has been working fine for a few months but has stopped reading the SD card. It still works on the internal memory fine. If I attach it to a computer you can read the SD card and remove or add files but the Studio still refuses to read it.Other than this recent problem I have been really pleased with the Studio. It is a really nice sound with the SE 530's if I am mobile and even better with the Alessandro Grados when I am at home. It sounds better than the roccoo but this seems much more robust as I have had that for over a year and had no problems with it at all.
There was several FW upgrades for the AMP3 so hopefully the Studio will do the same. Is anyone offering any after sales for the Studio anywhere as it has all gone very quiet on the Hisoundaudio threads.
