Hello.
I registered today, although I have been a follower of the Forum for a few years because I believe that there are people who know more than me about this world and I like to learn.
I have a question, after reading this post and realizing that not only my D400ES has problems with the PCM filters in conjunction with the different Sound Colors.
I consulted with "Mandy" from SMSL about this problem and since I still have time to return the DAC, she told me that there is no firmware update but she did not tell me that there will be one, so I ask you, Is it worth keeping the DAC or returning it due to the lack of respect on the part of SMSL in this matter?
