MSB Technology DAC Owners (Question)

I own an MSB Discrete DAC, two power supplies, paired with a LUMIN U2 streamer, via AES cable. All upsampling options are turned off on the LUMIN.

MSB Technology staff are out of the office until the new year, January 2024, hence why I am posing my question to all MSB DAC owners.

I noticed when I am playing music with various sample rates, the MSB Discrete display will, intermittently, show two horizontal lines/hyphens, followed by the letter “k”. The DAC does show the different sample rates in the display at times, but it frequently displays the aforementioned, followed by the letter “k”.

MSB owners, have you experienced this, if so, have you determined the cause?

I spoke to an MSB retailer today and they experienced it as well and they think it may be a result of the settings in some streaming services. My buddy who owns an MSB DAC thinks it may be the settings in the streamers or streaming services as well, but he hasn’t experienced this with his MSB DAC.

Thanks in advance!
