I'm a newbie and haven't found the answer so here I go. How would I switch between sources? Say I have a Weiss, Lavry or berkeley DAC w/ volume control and then I have an analog rig with a phonostage also with a volume control. I'd like to take the purist approach with no preamp but short of pulling my interconnects out of my amp to switch, what are the solutions to switch between sources without a preamp?
