    To make sure the battery keep the best situation, M17 will charge the battery first when it is work in DC mode, but it will not provide any power.

    also for some OP AMP , usually the SQ will be better when it works at higher voltage . sometimes this is the important reason why the desktop headphones amp will have better SQ even the output power is the same as a portable headphone amp.

    It is quite simple, in the Enhanced mode, 1, M17 is powered by extra DC power, there will be difference in SQ between battery power and DC power. usually we will say that the DC has unlimited power so the dynamic will be better and bass will be more impact. 2, Once the Enhanced Mode is...

    it is quite normal cause we start M17 in two years ago,also there are very bad situatiom to purchase almost every IC.

    M17 can't supports 768k when it work in DAP mode. it is limited by the FPGA's resource .

    Yes, you are right, XMOS 216 has more resource to handle more features . M17 is used XMOS 208 which has limited resource so we can't make it support MQA .

    We plan to sell some DC power to our user but may not in short time cause there are too many supply issue this year and it is very closed to Chinese New year.
