I have looked but cannot find the relevant needed specification, input sensitivity, for this very basic phonostage. All I can find of relevance is that the the maximum output appears to be +10dB at 1% distortion which is not, how can I say, impressive. Given the cartridge's rated output of 4mV (nothing unusual BTW) I suspect that your diagnosis amy be correct.
The Schiit has a rated output of 320mW into 300 ohms (the Senn's impedence) which should be fine. Actually the Sennheisers are really not all that difficult to drive even given their high impedence unless you are talking portable devices. I use 600s which are broadly similar to the 650s.
So I think it may be worth your while looking at some other phonostages even if there is a more substantial cost involved.
However having the volume control at 2 o'clock is not , in itself, a problem. But if you are still feeling that there is something important missing, then it could be.
