If you like the look of the pa7 as the pre/speaker amp and want simple then it should pair fine with their e30 dac https://www.electromod.co.uk/topping-e30-i-i-lite, sound-wise though I cant imagine you will notice a huge difference between that or the fosi stuff, the fosi does use a pot for volume control so may have issues at low volumes with balance that the pa7 wont have as I think it uses relay control although I could be wrong on that.
