In that price range, look at MHDT Labs lineup. I have the Orchid.
I also owned the Mytek Liberty. It didn't stay in my possession for long, too "digital" / analytical for my tastes. The Orchid is much closer to the sound of analog. A friend has the Topping D90 and it sounds great in his system. The Schiit Bifrost 2 is an affordable option, but it also had a little too much "edge" for me and didn't stay long. The same friend mentioned previously that has the D90 also had the Bifrost 2 and ended up keeping the D90.
Knowing what type of sound you're hoping to achieve would be helpful. These little boxes don't all sound the same.
