I'm curious. I want a headphone amp that sounds like my Tripath speaker amps. Headphone amps only need to push a volt or two, in my case into 32 Ohms.
What is the absolute lowest voltage 41Hz amp? The Amp11 can go down to 9V AFAIK ... is there any other amp that can run on less?
And if we go into funnier territory, could I use the Amp11's TC2000 chip as usual on 5V, and have it run 5V output devices somehow? I.e., drop the "high power" stage of the driver chip?
