Tim,
Now I really see why the Oppo was included from start ... I could not understand why you had started with a $1200 source in such system!
Not the balanced outputs, which are easy enough to convert, so much as the value. In this system, that $1200 source is universal optical transport, top quality asynchronous DAC, headphone amp and preamp. A lot bang for $1200 worth of bucks. Tone control would be nice, but the Dynas have low/mid/high filters that will allow for enough tuning...
