My DAC puts out a fixed 2.5 volts , so at some point I may try connecting it directly to Source 2 and use the gain as volume. Something tells me I'll prefer the preamp in place but I want to try it.
Yep, I’d also compare the DAC direct versus active preamplifier. I’m inclined to believe that the Zesto will be hard to beat.😊 You’ve put together a quite lovely audio system.
