We have our Reference DAC Display set to "On" and "Small" which means that it will show the Volume on top of the bit depth and sample rate. So, when playing a CD it will normally show "98" as the volume and "16 - 44k" as the bit depth and sample rate as expected.
While I have noticed that the bit depth/sample rate change to "0 - 44k" temporarily in between songs on a CD (using the MSB Reference transport and spinning discs) before going back to "16 - 44k" when the next song kicks it, yesterday I noticed something that was not apparent to me before.
Mind you, I don't normally look at the display other than when powering the unit up or placing a new CD in the transport, so the observation I will shortly describe might happen more than I think. Furthermore, I normally listen to rock music which doesn't tend to have any "quiet passages" during a song. However, yesterday I was listening to some Tudor court music (circa 1500s) which indeed does have silent/quiet passages during the actual track and noticed....
Observation: Whenever there was a break in the singing/music during the track such that there was a short silence (singers gathering their breath, etc.) the display would move to show "10 - 44k" or "11 - 44k" before quickly going back to "16- 44k". This appeared to consistently happen whenever there was a short silence during the track.
I found this odd since even if there is digital silence, I would think the bit rate and sampling frequency would still be "16 - 44k". I am speculating that maybe MSB's display shows the bit depth as the highest order bit that is set to one, but that is just speculation (and probably a question for MSB) which, to me, would be odd.
My question to those who have a Reference DAC (or a Select II) is if anyone else has;
1. Seen their display change to "0 - 44k" in between CD tracks?
2. Seen their display show <16 bits with a 44k sampling rate during an actual track when the music goes silent for short periods of time?
Thank you.
