USB transmission ....................................................................Asynchronization Build quality is definitely a step up vs some smaller/cheaper Aiyimas I've been messing with lately. Well, at least fit and finish - I can't comment on the internals.

Notice that I've turned on the "Peak" tracing as well to capture the highest values across the 8-average readings. Not unusual to see some 60Hz mains hum with harmonics getting into the measurements with unbalanced connections. We're basically looking at -110dB RCA and -120dB XLR noise floor and distortions otherwise.AAC ..............................................................................16bit/44.1 kHz_320kbps

Using the latest DSP chip with ST high-power amplifier chip, carefully designed and debugged, its distortion is as low as 0.0008%;

Just received the new Sabaj A20. This a brand new class D amp made with a dual Infineon Merus MA12070 and fully balanced.

You have the possibility to adjust the bass / treble, the amp also has some presets, I'm not a fan of it, I left it in "direct" mode. Size ...........................................................................280x63x260mm (WxHxD) The output power of the A20a 2022 is 170W (4Ω) / 90W (8Ω). It has more than double the output power of AO200 / DA-9 / SA300 / PA3. High output is possible with a dual power supply with a power supply voltage of + -34V (total 68V) for the MA5332MS chip. If you feel power shortage with AO200 / DA-9 etc., A20a 2022 is the best choice.Subwoofer output level..............................................................................2Vrms
