While this is an old thread, I thought I would post an alternative solution for newbies/used equipment market. Using a FiiO Taishan digital to analog audio converter (or similar) I was able to use the S/PDIF output. It is the equivalent of having the master cranked to max but offers a cleaner signal IMO. Going this route I was able to turn my power amp down significantly. Also, no longer need to boost signal in amp/effects path. The converter auto syncs at 96Khz. You can use a regular shielded RCA cable for S/PDIF connection. I used an old composite video cable and used the yellow video cable for S/PDIF and Red & White for audio. Two RCA to 1/4" adapters will be needed to connect to power amp and a USB power adapter for the converter power. This set-up can also be used to run into an audio interface that does not have an S/PDIF input or into a looper and maintain connection to your amp. No noise and wow, what clarity and volume!
