    O-Noorus D1 - TPA3255 PFFB Stereo Amplifier - Front Display, Tone Control (with bypass) and Remote

    Neither. It is rotated by 180 degrees from what you typically see. Min is at 1 o'clock, 50% at 6 o'clock and max at 11 o'clock. Not a big deal at all. .

    O-Noorus D1 - TPA3255 PFFB Stereo Amplifier - Front Display, Tone Control (with bypass) and Remote

    With most it does not matter much. But with some it is immediately noticeable. It always was.

    AIYIMA A70 Stereo Amplifier Review

    I like the external psu. There is absolutely no hassle in replacing it should it brake down. The amp will take virtually any voltage over a standarized plug. I have seen far too much gear went scrap because the built-in power-supply brakes down.

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    I don't see how you can use your iPhone as microphone for RAW... But - just to compare two AMPS, you can use laptop built-in microphone.

    Topping PA5 II Stereo Amplifier Review

    This should be completely isolated from the mains and not grounded.

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    But WiiM AMP doesn't cost <100 monies... It is in the region of $€£300-350 - and at that price point I expect certain level of performance... The load dependency of TPA325x is not something discovered yesterday. WiiM certainly invested a lot of money to design and tightly integrate the AMP...

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    The inaccuracies of frequency response are effectively the same, regardless of how hard the device is pushed.

    Cheap class D amps. Andrew Robinsons take.

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    If there is no PFFB loop, it not very complex (actually you need complex numbers though ;)) I don't have the exact (mathematical) tools needed, but I am pretty certain if you know the function that describes the output impedance of the amplifier and input impedance of the speaker, you can...

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    Voltage or Power levels are mostly irrelevant for this test. The transfer function will be almost identical if you swipe at 1W, 5W or 20W. It is only close to maximum power that some differences will appear.

    Complex impedance load amp FR influence - WiiM Amp review by Erin

    It's not irrelevant. Sometimes the other aspects will cancel the uneven response, but sometimes they will enforce it. What one should aim for is, where they have control, have neutrality. The chase for -80dB THD is meaningless, other elements introduce distortion orders of magnitude larger...

    Topping PA5 II Stereo Amplifier Review

    NAD amps are also based on Hypex modules. But they aren't cheap either...
