I bought an early unit several months before the Dirac update. As with some of the older OPPO players I knew the Sabre DAC would require some run in time. Before I ever listened to it I ran it 24 hours a day for 6 days. Didn't help. The digital glare was so excruciating even my wife noticed it. Out it went and taking its place is a TEAC NT-505. Worlds better. I will say the Bluesound app is superior to the one TEAC and Lumin use but the difference in sound is huge.
