[Dont say beats]

I have a pair of 250ohm dt880s and am looking for a new amp DAC. I've been using a fiio e10 which is working pretty well. But I tried my friends modi/magni and its noticeably a lot better than the fiio e10. I see people talking about the new vali and the o2/odac is also an option. Looking for some advice for anyone that has tried the o2/odac or the vali with the 880s
