Hellas,
i was wonderung if someone can direct me towards a solution for a boosting amp, to put between a tinysine dsp board (TSA1701, with ADAU1701) and the amplifier i choosed to use, which requieres roughly 2 volts input to be driven in full.
So far i came up with this "brilliant" idea PAM8304 dual amplifier board, which would be marvelous, if it could be a workaround, because it houses two of these little PAM8304 amps. Hence the question how good is this realy in terms of audio quality or would i just out in the next bug of noice between my amp and the dsp? (of course a would have to adjust the output by regulating it through the dsp)
The problem of the tinysine and also the minidsp 2x4 is there low output voltage of around 1V, which is great for lowlevel amps but can't realy drive other amps above that. And a real workaround, for a decent price i could not realy find or got someone a good idea of how to achieve an higher output?
Would be glad for some tips!

1 - do you need the full output? Try it first.
2 - use an op-amp input buffer - plenty of ready made boards. change the feedback resistors to change from unity to 2x.
Choose a board with through hole components if you're not happy soldering SMD.
