Brendan have a look at this link hear where David is comparing streaming devices
There are lots of good DACS in that price point from Zen, Topping, SMSL to name a few. Remember that the Zen Stream has USB and SPDIF out and can drive them separately if needed (I use both to to different headphone Dac amps).
I was chatting to someone that had recently bought the Zen DAC 2 SE and he was very happy how well it worked with the Stream, but also users with Topping being very happy with them.
I would make a short list and do some YouTube searching for Topping D30 pro, SMSL SU-9
Like I said so many options in increments of about $50 or so.
Have fun looking at the options
