Question on my DAC


I have an ARC LS27 preamp and recently bought a used Bryston BDA-2 DAC which improved sound quality significantly. Oh so satisfying...
However, I have a question about sampling rates: I stream music from Deezer and the new Amazon HD streaming service. It seems no matter what I stream, including remastered recordings etc, the sampling rate stays at 44.1Khz. There is also an LED that indicates it's "locked".  I can push a separate "upsampling" button, but the lock remains in place and also stays at 44.1KHZ. I don't see any "unlock" buttons and the user manual doesn't give a lot of information on that subject.  My source is a Bluesound vault and I use the coax output.
Again, I love the sound this thing produces so I'm not searching for better quality, just curious about how the sampling is supposed to work.
Thanks!

If you were to play true high res offering from either Amazon HD or from Deezer, you would see the Bryston DAC lock in at something greater than 44.1 kHz.   So for example, if you were to play MQA offering from Tidal via your Bluesound Vault, you would see your Bryston BDA-2 lock in at rates up to 96  kHz.
