I don't think 'hardware' based volume control is unique to just the iFi DAC.
In my case I can use my player App on iPad/iPhone/Mac to remote control Volume output from the DAC and the DAC hardware responds via a relay switched set of discrete resistors in it's attenuator circuit - separate from the DAC chip itself and fully in the analog domain - rather than dropping DAC 'bits' in the digital domain.
If the iFi remote Volume control is handled in its 'hardware' it's probably just dropping lower order bits within the DAC chip. Other DACs do this too with their dedicated Remote controls..... which ain't as bad as audiophiles think. If you have a 32-bit DAC and your source music is 16-bits or even 24-bits, you have several lower-order bits to play with w/o losing any audible resolution or dynamic range.
Does the iFi DAC have a separate hardware based volume control that resides OUTSIDE the DAC chip itself? What is it comprised of?
