The external amp that I have in mind uses Alps blue velvet.
Been trying to read about digital vs analog volume control.
Seems like digital control is preferred to minimize degradation?
You're trying to feed a normal integrated amp, i.e. it has a preamp with volume control, not just a power amp, right? In that case I'd use the fixed level output and regulate at the amp. In case of feeding a power amp there's no way around the HP-A8's volume control.
It depends on how digital volume control is implemented. It reduces bit depth, so I'd not use it if it uses less than 24bit internal encoding (the A8 should be fine in that regard). I prefer volume control on the analog level, either done by a good potentiometer or a relais-controlled resistor network.
