I will get a cheap pc to do the update. Anybody know what the update actually does?
I just plugged in my HD650's directly into the DL200 and was pleasantly surprised by the good sound quality even at low volumes around 30 at high gain or 60 at low gain. I'm using low gain at 65 now and it sounds really good. Going direct is giving me a bit cleaner and more upfront sound that works well with these headphones. It is a little lifeless and sterile compared to the OTL tube amp, but very sufficient. I feel like power is enough and I'm hearing a lot of details, more than with the tube amp, although it is presented differently.
