Volume disable is useful if you want to play DTS or HDCD files into a DAC, because ANY change to the bitstream will turn DTS into white noise and HDCD won't work. The code still does EXACTLY the same amount of work before or after the mod. When vol=100 (max) there is NO "digital volume" in circuit. Digital volume doesn't "squash dynamics" in normal use, but that's way off-topic :-) Finally there is NO error correction on ethernet transmission! - there is checksum processing which detects invalid/corrupt packets, but it can't correct them, they have to be retransmitted. So no, there is no additional processor loading. Corrupt packets are extremely rare on a properly configured LOCAL network. They are much more likely over the Internet. It's nothing like (for example) CD error correction or interpolation. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
