So my cheapie USB cable showed up today and I conected the A8 and the Pontus with it.
HOLY SCHNIKEYS!!!!!!!!!!!!!!!!
I had heard glimpses of what the Pontus could do with the I2S and Toslink connections, but this was completely transformative. The soundstage was indeed holographic. The treble was sweet, and just like people say, just north of being too relaxed. My recordings came alive like never before. Such depth, such musicality. I was blown away, it completely exceeded my expectations. And this is only Day 5!! You guys all say it is going to improve. I am completely stoked. Needless to say, this guy is not going back. Just ordered an AudioQuest Cinammon USB for tomorrow as well to upgrade that element.
