The use of the SB volume control is optional. The control operates in the digital domain, by changing the bits sent to the DAC or spdif The idea is to run your SB device into a setup that has correct gain staging. This means that you should have an active or passive preamp with level control between SB and amp/speakers. You then don't NEED to use the SB control at all. Alternatively use in-line attenuators into just a power amp to lower the level to the loudest you ever want to hear and then use the SB control for day-to-day tweaking of level. This way, you will generally never lower the control enough for loss of resolution to be a big issue. With the 24-bit control and a 16-bit original signal (say redbook CD), any lowering will at minimum impact the value of the 16th original bit - this is why HDCD won't be passed correctly via SPDIF unless vol is on MAX and replaygain is disabled. There's nothing really bad about (24-bit+) digital level control when used wisely. Sean has explained the ins and outs of digital level control several times - it's in the Audiophile forum. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
