Welcome, I am using a fairly cheap Chinese made tube Dac to hold me over until the Bottlehead Dac kit is ready, It is marketed under a few different names, Hilly, Grant Fidelity, and others. Cost less than 200 but sounds pretty good at 24/96. Many here really like the HRT Music Streamers, I think there are 3 models. I have heard the II+ model and if I did not already have a Dac I would probably invest in that one. Waiting for the Bottlehead kit, I hope it will be worth the wait. There are quite a few Bottleheads using the Audioengine products, hopefully someone will chime in!
Cheers,
Shawn
