Devialet 110 What Hifi review

[thumb5]

It makes no difference at what rate the Devialet works , as you attenuate digitally severly, you lose resolution. At some point it becomes audible.

As I understand it, the point that Jean-Marie was making was that if the digital volume control is done using 40-bit maths, it should have more than enough dynamic range to prevent any audible loss of resolution over the useful range of a volume control.  Assuming 16 bits is enough for normal music reproduction and you need (say) 10 or so bits for a volume control going from -60 dB to 0 dB, a 40-bit calculation should have plenty of headroom, shouldn't it?
