Pros: HQ audio, Spdif in and out,swapable opamps.
Cons: No dedicated headphone jack
Detailed, neutral, CRYSTAL clear sound. No extra noise, hiss or hum from PC, superb source for 96/24 sound.
The "VGA" on the left side goes for breakout cable that breaks it into 5 3,5 jack connectors where You can plug headphones.
Some people claim that included opamps can drive most headphones, some even said it can drive AKG K701, I tested it and i can confirm most headphones do well without additional amping but AKG's need more, way more power then stock opamps can generate.
Build quality is extremly solid, just check the picture :)
