This graph shows that the D 3020’s left amplifier channel, with two channels driving 8-ohm loads, reaches 0.1% distortion at 42.6 watts and 1% distortion at 52.6 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 58.8 watts and 1% distortion at 63.5 watts.

THD+N from the amplifier was less than 0.007% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –81.39 dB left to right and –76.92 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –109.14 dBrA.—MJP

Hi. Thanks for the review. In it you state: "you cannot stream FLAC or other lossless formats"
I'm confused because later you talk about how great it sounds with FLAC files. While the manual doesn't state what formats are supported, I'm never heard of a DAC that doesn't decode FLAC or ALAC. Can you please explain "you cannot stream FLAC or other lossless formats?"
