unfortunately they are terrific when driven by the little tube amp we share with the guy. it was nice with the rme adi2 dac too, still a bit flat and dull sounding. much better than i remember from a previous vanilla hd800 (not hd800s) listening test. rip my wallet lol
i'd probably keep the focal though, it's nice for the short time i use headphones
my host though, i think i changed his mind. he has two headphones for his desktop setup: hd800s and denon d5200 (one of the best closed back i know, and i had the d7200 for a year, the little brother sounds more balanced, natural and never gets in the way while the d7200's bass bloat was a pain in the ass sometimes), but his wife often takes his place for some home office stuff, so he can't listen to music while his wife is working. so he wanted a wireless to connect to his phone. he ordered the sony xm4 a few weeks ago, found it not really enjoyable compared to the hd800s and the d5200, sent it back before the 14 day return window expired. he will get the beyer amiron wireless next week on a loan from a dealer we know, but he already knows that he won't buy it. why? because he plugged the d5200 in the lotoo paw s1 i showed him today, and it really was awesome. so now he's about to get a lotoo paw s2 (the newer model) and call it a day. and i missed out on a d5200 ebay auction tonight lol, maybe next time
btw i read a nice review on your dali's:
