Frequently Asked Question
Firmware 5.30 has a period of silence/no sound from starting position. However, 5.3C is fine?
Answer. As 5.30 performs digital signal processing processing of MQA but not with non-MQA audio, the hardware needs to momentarily re-configure. CDs normally have a short silence between tracks which would still carry MQA markers. If ripped without those silences included before each track (ripper settings) then the hardware needs time to reconfigure after the track started playing. Streaming MQA files tend to include a short silence before track start. So the gap is of 0.3 sec.
With 5.3C, when switching between the GTO filter and MQA filtering both always apply digital signal processing. Therefore the hardware is always configured the same. Under this scenario, the switching delay between MQA and non-MQA audio is minimal at 0.1 sec.
