I thought Hugo used a more powerful FPGA and had a different sound signature than the Mojo though. I may be mistaken but I thought I remembered reading a review that said the mojo was darker and more musical than the Hugo?
More musical? Never!
All opinion of course. I have both and will say very very close in sound. Be surprised if many would like one and not the other. Hugo slightly more clarity which some may say tiny bit less warmth.
But Hugo adds mains charging, Bluetooth streaming from phones, and full size headphone jacks. Also weight and lack of input last selected.
Swings and roundabouts, I like Mojo with iems and Hugo in Lounge with Headphones.
