It can power the 600 adequately, but the pacing and some fine details probably won't be ideal. The stronger plug doesn't output more power unless you need it. Most others have been using the normal one to drive the 600 ohm models and I'm guessing one gets slightly better results with the stronger plug. But I still trust the subjectivists on this one. The O2 is a good amp--I currently own two and plan to sell one--but I don't have a hard time believing that a Violectric or DAC1 is better.
Do you have a suggestion as to a specific Violectric or DAC1 that would be good for a newbie like myself? Or is that getting into the range of unwanted price increases?
Realistically I may just take a 250 ohm and be happy with that.
Also, I really appreciate the time you've spent on me today. Thanks for that.
