I don't know what your source of music is, but for me, I use jriver for playback of digital files on a computer with a Benchmark DAC. I can lower the gain through jriver or by making internal adjustments through the DAC. This may be an option for you.
Too much gain in preamp
I have the Edge S-1 preamp. I'm not sure what amp this would mate well with but when I use it with any of my SS amps I have way too much gain. When I turn the knob up 20% its full up. Obviously it is hard to set the volume with this situation. Should I be using this with a different amp? Or reconfigure something internally? Anyone know how to contact the manufacturer?
