Hello, I have a fresh SF8008 Supreme Twin and I have a problem with the sound quality. I also have DVBT2 antena on my TV and sometimes I switch between DVBT2 and satellite receiver (both HDMI) for comparison. On the 10-year-old VU solo2, the sound from the satellite was allways better (on higher frequency) than from the DVBT antenna (same HD channel), so I was surprised that the SF8008 sound has the same low quality as on DVBT (downmix AC3 on/off, HDMI autolevel on/off ). I tried to play the same concert from a disc through AV Yamaha at the same time connected over HDMI from both, the difference in the disadvantages of the SF8008 is noticeable there. It seems to me as if the octagon had its highs cut, or the VU had them amplified. I tried OATV 7.3, updated to the latest OATV 7.4 + Define - no improvement. Any ideas for a solution?
