thanks project86, i appreciate the help, just 1 final follow up question, i currently run my tube out to an external amp (matrix m stage) and am unsure on something, the volume potentiometer on the actual td11, for optimum performance, should i max it out and only adjust the volume on the external amp or leave it at around lets say 3 o clock on the td11 and adjust the knobs on the m stage even further?
i feel like if its max volume it puts less of a strain on the m stage but on the other hand, i think running at max might make the signal run too hot so to speak and introduce clipping and such and the m stage would then be boosting a degraded signal, what do you think?
Don't worry about strain or anything like that - just go by what sounds best to you. If I recall correctly, turning the knob to max equates to 6V which will be too hot for some amps and just fine with others. If you run the volume knob at slightly less than half, you'll end up with a more typical 2V to 2.5V which will definitely work fine.
If you have the non-USB M-Stage with 2 analog inputs, you can connect the "DAC Direct" output of the TubeDAC to one input, and the tube out to the other input. The DAC Direct is fixed at 2V so it can be your reference - see if switching to the Tube out with hotter levels causes any problems, or any improvement.
