VisuthI'm wondering the same since I just ordered the Aune T1 last night :)
From what I'm reading, even if you disregard the fact that the Aune has a DAC included, it is still the superior option, although if this amp reaches lowest price it'll be 50% of the cost.
tylerbrainerdSame... looks like I'll have to do some research tonight. At least we have a day to decide.
I've also heard that while the Aune T1 is a great DAC/AMP, it doesn't quite reach the quality of a Schiit stack or an Objective2+ODAC. It's more of a flashy, midrange device. Makes me wonder if I should just opt for this.
VisuthBravo will be a good match with the DT990 as it is designed for high impedance headphones.
but the K702 are hard to drive, low impedance headphones. Bravo will not cut it, and neither will the Aune T1 .
SyndicateWhile the O2 is far superior to the Aune and Bravo, it doesn't mean the O2 will sound better.
Most people find the V-shaped sound signature of the DT990 a tad too bright sometimes.
O2 may not be a good choice in this case.
VisuthThe Aune has dip switches to control the amp, for harder to drive cans like the 702s. The +16db setting works very well... you'll have more than enough volume/dynamics. They are 62 ohm nominal impedance, so yes... rather difficult to drive properly with some amps. The Aune can definitely handle them though. I own 702s and love listening on my Aune.
