Hi
I'm looking into building a proper DAC, just curious since the option is available, if there is any reason to use 4vrms out or stick to standard 2vrms? Would TSE clip with 4vrms input?
I don't mind turning the knob all the way up though, just curious if any more output will be seen with some gain on the input without clipping.

Depends on your speakers. If they are >90db efficient (recommended for SET amp like Tubelab SE), 2V should be fine.
I happen to have both of my tubelab SE's on the bench right now; a 45 version and a 300B version.
The 45 version clips at approx 1V RMS input and the 300B clips at roughly 1.5V RMS input.
I'm just eyeballing the sine wave for distortion/asymmetry on the scope at 60 hz and 10Khz.

I don't know, but with my 2V source I simply could not get the 300B to go into clipping. I just assume that maybe your voltages are not high enough.
