Apple iPad music streamer

Ok question from a newbie here:

i recently got a Bluesound Node Streamer/DAC for my home stereo and stream from my ipad or iphone over wifi.  I stream Tidal - Love it.    In my office i just connected an ipad via headphone jack to an amplifier.  Sound is clearly - okay not great.  Trying to decide in my office - to either 1) get a streamer for there too or 2) get an external DAC and run my ipad thru that to my amp.  It sounds like option 1 will provide higher resolution audio but it also costs more.....thoughts? Thank you, 

I have tried about all. DAC first, external streamer second. Both necessary for great sound.

There are too many variables here.  What’s your equipment in your office system?  Adding a streamer will get you better sound versus streaming through your iPad/iPhone, especially if you’re using the headphone Jack.  Yuck.  I even bought a higher-quality lightning adapter to USB and hooked to a good DAC, but using a separate streamer was at another level entirely.  Last, give Qobuz a free trial — most of us much prefer it to Tidal and they have a lot more hi-res content and none of the MQA BS. 

Using my iPad 2 as a streamer, with loaded playlists from Mac Book Pro

works well with Apple camera dongle with AudioQuest Carbon USB to Schiit Bifrost 2 DAC sometimes interchangeable to PS Audio DAC III.
