Digital Volume Bit Stripping?
Answered
With the volume set to variable on Nano, there appear to be 50 "clicks" from off to maximum. I presume at maximum variable volume there is no bit stripping. But wondering how many clicks down from maximum bit stripping starts. Asking the question because Nano is connected to integrated amp with analog volume control. But the amp doesn't have remote. If the digital volume of the Nano is always lossy below maximum, I think I'd just use fixed output mode and get off my butt to change volume. But it there is a range on the digital volume where it retains all the bits, it would be useful. That way I could set the analog volume dial on the amp at the sweet spot to take advantage of Nano remote control volume. Thanks in advance for answer. BTW have had Nano for two months, really blown away by how much it offers in a tiny package.

There are no audible bits discarded when using variable volume control, internally the DAC(s) are processing in a 32bit environment which give you the room / overhead to adjust the volume with no impact.

Thanks for the clarification, Seppi. When you say "no audible bits discarded" does that mean bits are being discarded, but they are inaudible, or that no bits are being discarded? If a 32bit environment allows for full range of attenuation without losing any bits...that would be a game changer...

To reduce a digital signal you have to remove something, these are removed in the 32bit environment. I don’t have the full technical details but someone from Sonos might be able o chime in.
