Hi, I am fortunate to have a Blu Mk II on trial just now. It is partnered with my Dave via dual BNC @ 705.6 kHz. Imagine my shock and disappointment when I found that it will not play a cd or cdr more than 78 mins long.( my Hi end Marantz dealt with up to 80 min discs without problem). Upon reaching the 78 minute length, the sound firsts starts to distort (like crackling bacon getting louder and louder), then the unit freezes up. Maybe mine is faulty, but even though the sonic results are mind blowingly superb, this is a major drawback in me actually confirming a purchase. Please give me any feedback on this. Thank you.
