Pros: Warmth, Detail, Speed, and Accuracy
Cons: No optical input, nothing else.
I'm going to keep this review brief and to the point. This amp is freakin' awesome for $250 and it has a high/low gain meaning it's capable with almost any type of headphone you can throw at it besides orthos. I use it with my DT880s and they sound way more fun and not boring like they used to. So ya, just buy this amp. There is no transformer hum and the noise floor is very low. So disregard earlier reviews because some of the first units produced were defective. Best $250 I've spent in the past few years. BUY IT
