SABAJ A20a Balanced Stereo Power Amplifier Receiver 2 Infineon MA12070 Chip Hi-Fi Class D Amp 150W x 2Ω XLR RCA for Home Speakers with Remote Control

Product Information

A large number of audiophile-grade audio components are used to enhance the subjective sense of hearing; I'm running it right now on my "test bench" (aka in the garage) before I move it inside. I'm connected to some Snell K/IIs I keep down here for just such an occasion. This is my second amp based on this chip. I had already reviewed a fully symmetrical dual Mono MA12070 that I had built a few months ago.

SNR ..........................................................................................................103dB Low pass cutoff frequency...................................................................70~200Hz For the volume pot for volume control, it is usually necessary to use a taper A characteristic whose resistance value changes with a logarithmic curve. Just received the new Sabaj A20. This a brand new class D amp made with a dual Infineon Merus MA12070 and fully balanced.

One amplifier chip per channel

The A20a 2022 does not have the abnormal noise from the power supply unit or the abnormal noise of the speaker output that I reported on the Sabaj A20a. The color display screen and user-friendly operating system are easy to understand, equipped with full-function remote control function; Overall, this is a phenomenal performance level for a modern PCM DAC for both RCA and XLR line-level outputs. SBC ..............................................................................16bit/44.1 kHz_328kbps Since I own almost all TPA325X in the market and some Hypex Ncore and Purifi at home, I can tell you that it is pretty good even very good in comparison ... for the little that I have heard.

Subwoofer output level..............................................................................2Vrms Bluetooth specification...................................................................................5.0 Weight ..........................................................................................3.3kg/7.28lbs AAC ..............................................................................16bit/44.1 kHz_320kbps 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.The problem is that they are using the wrong volume pot for volume control on their audio equipment. Standby power consumption.........................................................................<0.5W
