It's been over 30 days since I purchased the STA200 and I've ironed out some issues with my system. I had been using an Apple TV 3rd gen via the optical output to the NAD M51 DAC and switched to the USB input connected to an old Windows laptop.
The sound is now phenomenal. I am seriously convinced that you're not going to beat this amp for $500. Bass is full and tight. I ditched the Doge 8 and am running the M51 directly into the STA200 and there is no harshness, but the highs are extended and detailed.
