I was really thinking of grabbing the UD-H01 from Richer sounds (£150/$250) but after reading the thread I'm a little reluctant, my original choice was the Objective2 + ODAC, I plan to get an O2 for the amp side of things shortly, and would have it paired with the UD-H01, using Grado PS500s.
Little worried though, I have time to sit on it but the driver issues with Foobar (my main computer source) might just turn me away, along with those saying the mids lack.
don´t judge this DAC too hard. for the price you pay you get a lot. i use it with the xlr outputs and active monitors, and there are no mids lacking. by the way, this device is no dedicated headphone amplifier, it is a dac with an additional headphone amp. no more, no less ...
I tried it with 600 Ohms cans -> dead silent. But why not with low impedance headphones? whatever!
